phosphorus should be named as metalloids if selenium is named so. All "diagonal carbon group" (C, P, Se, I, even Rn which have some cationic behaviour) exhibits intermediate proprties between typical nonmetals and typical metalloids ("diagonal boron group", especially: B, Si, As and Te). I think it is "unjust" when selenium is named as metalloid and carbon and phosphorus "only" nonmetals. Phosphorus have lower electronegativity than Se and C and should be also named as "weak metalloid". Ionic sodium selenide (similar to oxide of Na, easily reacts with water) and telluride (highly soluble in water). Black phosphorus have much higher melting point (about 600 C) than gray selenium. Very hard to melt, grayish-black lustrous graphite which is better conductor of heat and electricity (often used in electrodes, such as harder glassy carbon) than many metalloids at normal conditions definately does not fit to nonmetals, but to metalloids (semimetals), such as gray selenium and black phosphorus. Naming selenium as (half)metalloid and classifying carbon and phosphorus as only nonmetals is even flawful and should not be used. Even insulating and transparent diamond (less metallic than graphte form of carbon) is not so much like other, typical nonmetallic elements (density compared to atomic mass, heat conductivity, melting point, hardness - they are associated with metals (especially heavy), but diamond is in it better than all examined metals! (paradox)). It is rather like compound of metal and nonmetal like aluminium oxide, which can also be very hard.

5266:: To some extent, as you alluded earlier, a nonmetal is something that is not a metal. The implication being that metals have so shaped civilisations over thousands of years that everyone, including lay readers, know that metals are shiny, usually heavy, and good conductors of heat (a hot car under the sun) and electricity (lightning rods, etc). So the term “nonmetal” just by itself conveys much information already. The Br mention is meant to suggest that while Br is the only liquid metal, it is so volatile that one usually encounters it together with its fumes i.e. gaseous vapours. So the nonmetals are almost all either gases or solids, unlike the metals which are all solids, bar one. Otherwise, having to account for Br as the only liquid nonmetal becomes rather exasperating in terms of prose construction. I’ll look at this some more along the lines of your suggestion, and maybe post, revert, and ping you a link, if something good comes of it (or not). 5214:“In chemistry, a nonmetal is a chemical element that generally lacks a predominance of metallic properties. They are nearly all gases or solids at room temperature, such as oxygen or sulfur. The only liquid nonmetal, bromine, is usually topped by a layer of its fumes. They typically lack the shiny appearance of metals, have low weight, and are poor thermal and electrical conductors. The solid nonmetals are brittle to crumbly, cannot be flattened into sheets or easily drawn into wires without shattering or breaking, and have low to no structural strength. Nonmetal atoms are moderately to highly electronegative; they tend to attract electrons in chemical reactions and to form acidic compounds.” 1179:

because it lies more to the right (belong to carbon diagonal group, not to boron diagnonal group, such as silicon)).Phosphorus has the lowest electronegativity in Pauling scale from all of them, it is quite similar to metalloid arsenic, maybe even more to nonmetal nitrogen. White phosphorus deforms view on metallicity of phosphorus. In addition, black ("metallic") phosphorus is the most stable allotrope of this element. Phosphorus (gaseous elements: hydrogen and radon also) have lower electronegativity than some heavy metals, especially gold. Phosphorus also have significally lower electronegativity than carbon, selenium and iodine.

263:

elements and its hydride is not acidic like hydride of sulfur, ("infamous") selenium and even typically metalloidal tellurium! Black phosphorus is, in addition, the most thermodynamically stable form of element number 15. Not this low-melting whitish waxy poison known as tetraphosphorus. Metalloid arsenic also has highly nonmetallic allotrope (unstable and really light yellow arsenic), but main form of As has even better electrical conductivity in normal conditions than manganese. Phosphides are also often quite metallic, they are similar to arsenides.

1174:(C, P, Se, I) are significantly more metallic than nonmetals on the right of then, but less metallic than typical metalloids on the left side of periodic table. Most stable form of semimetalloids appear as greyish(-black) solid with lustre similar to metals (graphite, black phosphorus, grey selenium, crystalline iodine), unlike main forms of nonmetals. They are also better electrical and thermal conductors (it is significantly less marked it the case of iodine). Lighter semimetalloids have higher melting point than heavier (graphite : --> 5375:, fyi that I’ve incorporated your good suggestions here to the extent that I feel is practical and appropriate. I’m reluctant to say something in the lede about "metalloids" as a sometimes third class (notwithstanding they behave chemically as nonmetals) given the lede is supposed to give the lay reader an overall impression of the subject matter, and it currently does that. In my view, more details about the pesky or mysterious metalloids can be left to the main body of the article, as is currently the case. 4021:

same in chemistry with regard to what is a metal(?), there being no rigorous definition. Thus the topic sentence of the next paragraph in the nonmetal lede says, "While the term dates from at least 1708, it has no widely-agreed precise definition." OTOH metals have an average density of ca. 9.5 gm/cm3 whereas the nonmetal average is ca 1.8 gm/cm3, noting there are light metals such beryllium, magnesium and aluminium, and relatively heavier nonmetallic elements such as antimony, and tellurium.

3950:. It also seems to me that defining a nonmetal as something that is a not a metal is a redundancy that is further inconsistent with the spirit of plain English. It further imparts nothing to the reader since it requires them to know what the (common) properties of a metal are. Probably most people do and since two of these properties are a shiny appearance and good electrical conductivity there is scope to erroneously conclude that graphite (carbon) is a metal. 3239:. Thank you. I didn't see these comments because, oddly enough and up to now, the nonmetal article was not on my watchlist. I appreciate your interest and advice, the basis for which I understand. I'll add something about this to the compilation of unstated FAC "rules" and expectations that ought to be made visible to all potential FAC nominees. I'll share it at FAC talk after nonmetal attains its bronze star, if not this time then at a subsequent FAC. 1878:, the author of the cited work uses the electronegative/very electronegative terminology only for what we call the reactive non-metals. Elsewhere he uses the standard "noble gas" nomenclature. Hence "Non-electronegative nonmetal (noble gas)" wouldn't be kosher. That aside, the expression "non-electronegative" would be awkward since at least Kr and Xe have electronegativity values, and it is these values that the distinction is partly based on. 31: 4645:, shininess, and ability to conduct heat and electricity. They don't have the characteristics of metals, which are typically shiny silvery-gray solids; moderate to good conductors; and can be molded, shaped or hammered into thin wires or threads without crumbling or shattering. Nonmetals may have a metallic, colorless or colored appearance, with about half being gases and half being brittle to crumbly solids. They are moderate to high in 2331:(2) The colour categories, which incorporated metal-metalloid-nonmetal, were dropped from the lede PT in the FA periodic table article for various reasons including, as I understand from my reading of WP:ELEM, to provide more flexibility in related articles. Certainly the concept of metal-metalloid-nonmtal exists but its application in the literature, compared to metals-nonmetals, is not consistent. Even so, there is still a an FA 739: 718: 698: 658: 633: 610: 594: 569: 553: 537: 506: 470: 3298:

sometimes counted as nonmetals, are rather OK such conductors. For thermal conductivity, metals range from 6.3 W m K to 429 for silver. The thermal conductivities of the following nonmetallic elements fall within this range: B, C, Si, Ge, P, As, Sb. The third sentence in the lede does say however, "Unlike metals, most nonmetals are poor conductors of heat and electricity."

4997:

Consequently, which elements are recognised as nonmetals depends on the classification criteria used by each author. Fourteen elements are effectively always included and up to about nine more elements are frequently to sometimes added, as shown in the accompanying periodic table extract. Some authors classify borderline elements into an intermediate category of

4039:, I interpret it to mean "having relatively low mass" (i.e., low atomic mass, which I, Xe, and Rn certainly do not have). If "having relatively low density" was instead the intended meaning, I would suggest rewording or relocating. This ties in with YBG's comment: especially in the opening sentence, we want a definition that accurately describes an element 1592:"It has a varying half-life length, depending upon atmospheric conditions (temperature, humidity, and air movement). In a sealed chamber with a fan that moves the gas, ozone has a half-life of approximately a day at room temperature. Some unverified claims imply that ozone can have a half life as short as a half an hour under atmospheric conditions." 2092: 2049: 1618: 846: 811: 363: 1330:

nonmetals. The same is true to black phosphorus and grey selenium. Iodine also looks like a metalloid, not like a nonmetal. Carbon exhibits borderline metalloidl and nonmetallic properties, such as phosphorus and selenium. I think that it is better when C, P and Se (not only Se) are marked as "half-nonmetals" and "half-metalloids".

5154:"In chemistry, a nonmetal is a chemical element judged to have a predominance of characteristic properties such as being transparent or colored; having a low weight; low to no structural strength; poor thermal conductivity; poor electrical conductivity; low melting point; low boiling point; and a tendency to form acidic compounds." 4750:

heat. These problems go away by distinguishing between typical and less typical nonmetals, consistent with the fact that nonmetals show a variation in the degree of their nonmetallic character. Describing nonmetals in terms of what they aren’t is not plain English, and should be mostly avoidable, in my view, with careful crafting.

1795:(a complementary and arguably non-controversial term) is a more natural way of categorising the nonmetals. The foundations of nonmetal chemistry rest upon the reactive nonmetals; that some of the noble gases could form compounds was not discovered until 1962, and since then less than 1,000 such compounds have been synthesised. 1334:

nonmetal, but its level of metallicity is much more similar to iodine, a "diatomic nonmetal", not to other polyatomic nonmetals (C, P and Se). Radon (monoatomic nonmetal) and hydrogen (diatomic nonmetal) are more metallic than fluorine (diatomic nonmetal). I think that division to six metallicity classes could be better:

1784:

agreement that they share a common attribute of being "reactive" nonmetals, in comparison to the noble gases. For example, the terms "less reactive", "reactive", "typically reactive", "more reactive", "highly reactive", and "most reactive nonmetals" are all found in the literature in connection with non-noble nonmetals.

6339:

A nonmetal is a chemical element deemed to lack a preponderance of metallic properties such as luster, deformability, good thermal and electrical conductivity, and the capacity to form a basic (rather than acidic) oxide. Since there is no rigorous definition of a nonmetal, some variation exists among

5408:

What does "near-universal" refer to? Does it mean almost every nonmetal is used in at least one of these applications, or does it mean that almost every one of these applications involves a nonmetal? The reader should not have to stop, in the lead, to sort out what a sentence is saying. As written,

4911:

is the fundamental difference. The Lead seems to be dodging this because it is deemed to be too technical perhaps? But I see no way round it. As it stand, the article is not accurate and this is a major problem. Don't dump accuracy in favour of simplicity or you might just as well say metals are made

4906:

in metals. The tensile strength of metals, their high melting point , opacity, ductility and conductance are all because of that bond and an understanding of the metallic bond requires quantum theory. Non-metals (and the term is informal) show a broader variety of properties because of they way they

3836:

Among other nonmetallic elements, the definition accommodates the noble gases, the halogen gases F and Cl, the halogen liquid Br, and the residual nonmetallic gases H, N and O, since these are all crumbly if frozen. The definition further includes physical and chemical properties, as would seem to be

2212:

apart from other problems, the current lede image has these formatting issues: (1) naming provocatively incorrect; (2) red bg color for matalloids does not match current enwiki standard; (3) using white for a regular subclass (1 of 4) is inconsistent, same color is (more correctly) used for off-topic

1513:

Division looks quite good! The least typical of "typical nonmetals" is sulfur of course, but has less metalloidal properties than near-metalloids. Can polymeric (non oligomeric, such as octasulfur) sulfur be stable at STP? At higher temperatures sulfur is more "metalloidal" because it polymerizes and

has asked me to take a look at the prose. I am delighted to accept; this is an important article on a subject I am fascinated by and which is dear to me. Could I ask regular editors to watch what I am doing; even though I have read the FAC and this talk page, I might inadvertently change the meaning

4533:

Yes, it might be optimal to keep comments on the peer review, but now that this is here, copying it over would just create a jumble. It might be clearer if, once we get this sorted, I just add a link there back to this discussion here, so everything is included without the need to copy. I understand

4515:

Also, as much as I'd like to engage, I don't expect to have any significant free time for the next two months, so my contributions there will likely only be a few isolated comments and responses. Moreover, I'm happy to offer a second opinion on more generic content (or some crossovers with physics),

1329:

Graphite is defintely not a nonmetallic substance. It has very high melting and boiling point, its electrical and thermal conductivity is far much more similar to metallic than nonmetallic. In ddition it is metal-like looking and grey in pure form. Graphite itself passes better to metalloids, not to

4749:

The proposed adaption is unintentionally misleading where it says, "They don't have the characteristics of metals, which are typically shiny silvery-gray solids; moderate to good conductors." C, a nonmetal, is a shiny gray solid and a good conductor. H, a nonmetal, is a moderately good conductor of

is not required. The definition (now) has a simple and relatively easy to follow sentence structure. It is written in plain English, noting that technical terms are permitted in plain English where there are no plainer equivalents. Since the subject matter itself is technical, a few technical terms

3197:

If I were you, I would not resubmit next week. After working through the ce you were doing and this feedback, it may be wise to contact one of the people commenting on your second FAC and ask for them to go over the article once more. A nomination that reviewers feel comes too fast after a previous

1798:

While the properties of the reactive nonmetals are diverse, the overall contrast with the noble gases is marked. And the reactive nonmetals are regularly distinguished from the elements commonly recognised as metalloids (B, Si, Ge, As, Sb, Te) despite the predominantly non-metallic chemistry of the

1497:

4. This division is close to the current categories. Alkali metals, alkaline earths, lanthanides and actinides ≈ strong metals; TMs ≈ typical metals; poor metals = poor metals; metalloids = metalloids; polyatomic nonmetals ≈ near metalloids; diatomic metals ≈ typical nonmetals and strong nonmetals;

1325:

Graphite conducts electricity, but it does it in a different fashion than metals do. It has unbonded electrons which are not part of a metallic bond. This is why it is a better conductor the hotter it gets, whereas metals tend to be poorer conductors when hot. So it is a conductor but not due to

1167:

Sulfur (polyatomic nonmetal) is less metallic than iodine (diatomic nonmetal). Iodine belongs to diagonal carbon group, sulfur to diagonal nitrogen group. Sulfur has lower conductivity of electricity and heat than iodine, sulfur looks nonmetallic, but iodine looks greyish and has metal-like luster.

5456:

Is "by each author" redundant ? Other than that, I'm satisfied with the readability of the lead and will move on to the body starting tomorrow. I am still concerned about the "always, frequently, sometimes" construct, as it may still feel too synth-y to get by FAC, but I will propose a way to fix

5322:

digestible, clear, thorough and understandable as a non-chemist (although I still think the fumes are adding verbiage that is unnecessary and lost on a general audience). If others are satisfied, I'll continue tomorrow (doc app't today) my line-by-line, at the peer review, but wish others would be

4020:

5 gm/cm. The intended meaning of "light", given most metals are heavy, is "low density". In what sense were you saying no one would agree that I, Xe or Rn are relatively light? The "relatively" qualifier is there in the sense that there is no rigorous definition of a nonmetal. The situation is the

3315:

Changing the article title to "Nonmetal element" would be helpful. The first sentence of the lede makes clear that this is specifically about elements, but then abandons any readers who are looking to learn about materials that are non-metals in general; they have to scan the whole article to find

3293:

In the first sentence, stating the poor electrical and thermal conductivity would be much more helpful than the rather technical mention of tending to form acidic compounds, which makes the noble gasses and ammonia feel unwelcome. The pure semiconductors are poor conductors compared to metals, and

1333:

Terms such as "alkaline earth metal", "polyatomic nonmetal", "diatomic nonmetal", "halogen", "noble gas" do not indicate metallic character. Beryllium is a meta-metal (metallic element with some mrked (chemical) metalloidal properties), but not a metalloid (such as aluminium). Sulfur is polyatomic

5052:"some ..." (ouch) properties lists. Being science, still no predictions are (can be) made for lesser known elements. For edxample, what about the heavy halogens and nobles? How can they be excluded/included from these statements/claims/notes if there is no scientific base for these two properties? 4984:

Although the majority of elements are metals, many nonmetals are among the most common elements in Earth and the universe. Two nonmetals, hydrogen and helium, make up about 99% of ordinary matter in the observable universe by mass. Five nonmetallic elements, hydrogen, carbon, nitrogen, oxygen and

3550:

The Goldhammer-Herzfeld ratio for an element = R/V where R is the isolated atom’s molar refractivity and V is the molar volume for the bulk element. The ratio has no units. It is a simple measure of how metallic an element is, metals having values ≥ 1. It is proportional to density (Edwards &

3297:

I mention a tendency to form acidic compounds as I feel it's important to say something about the chemistry of the nonmetals. I haven't included poor electrical conductivity in the first sentence of the lede since graphite is a rather good electrical conductor, and arsenic and antimony, which are

2953:

This sentence can mean two things. I think it's meaning to say that there are a few nonmetals that are difficult to measure: maybe because they have a low life time. It could also mean that some are harder to place in a category, but then it would be redundant with the second sentence. The second

1783:

It looks to us that the most widely accepted and long-standing categorisation of the nonmetals, at least conceptually, is a division into noble gases (an IUPAC-approved term) and, by default, "the rest of the nonmetals". There is no widely agreed terminology for the latter but there is widespread

6324:

A nonmetal is a chemical element that has low density and moderate to high electronegativity. They also lack metallic attributes such as luster, deformability, good thermal and electrical conductivity, and low electronegativity. Since there is no rigorous definition of a nonmetal, some variation

version, the article has undergone a full rewrite, as in: from scratch. Also, there are multiple FAC and similar targeted discussions since. Well, one piece de resistance I know of: while color and state of matter are not defining nor distinguisihing for nonmetals, and not analysed as related to

4996:

dates from at least 1566, there is no widely-agreed precise definition of a nonmetal. Elements near the borderline between metals and nonmetals on the periodic table often have properties characteristic of both categories, so that different classifications can be justified by different criteria.

3832:

The definition first refers to the relative lightness of nonmetals since the heaviness of naturally occurring metals such as gold, copper, and iron may have been noticed in prehistory and, in light of their malleability, led to the first attempts to craft metal ornaments, tools, and weapons. All

iodine). Carbon has also some similarities to silicon and boron (very high melting point, formation of hard allotropes (glassy carbon (7 Mohs), diamond (10 Mohs), carbides, borides and silicides are often very hard, names of these three elements end at "-on", carbon has less metallic properties,

6450:

About half of nonmetallic elements are gases; most of the rest are shiny solids. Bromine, the only liquid, is so volatile that it is usually topped by a layer of its fumes; sulfur is the only colored solid nonmetal...Nonmetals that form giant structures...(e.g. silicon), have higher melting and

6344:

The "after" version is less prescriptive and more in keeping with the literature, which tends to focus on what nonmetals aren't rather that what they are. It also removes the reference to electronegativity. I cannot see any easy alternative place in the article for the accompanying density v EN

5162:

I’ve retained "colour" since 4 of 23 elements or 1 in 6 of elements within scope of the article are colored; conversely the fact that 3 of 95 or ca. 1 in 32 metals are known to be coloured is effectively meaningless. Color for nonmetals is significant in that the band gaps of the semiconducting

4446:

The lead sentence has been recently changed to read "a nonmetal is a chemical element that is typically a colorless or colored gas, such as oxygen or chlorine, and a poor conductor of heat and electricity." I see at least two major problems with this phrasing. First, nonmetals are a variety of

3266:

I’ve just read your remarkable feedback. The article has been considerably refined since then. I’ve responded to your comments in any event given how much care you took in providing them. Quite impressive. Thank you. Sorry about mucking up some of your bullet formatting. I was getting some odd

1806:

For reference, the updated article includes a table of alterative nonmetal categorisation schemes found in the literature, none of which have attained widespread use. Knowledge (XXG) has used two of these schemes in the past namely (1) other nonmetals, halogens, noble gases; and (2) polyatomic

262:

Se, P and C are in the same level of metallicity. They can be marked as "half-metalloids" and "half-nonmetals". Phosphorus has even lower electronegativity than some heavy metals (such as gold) and black phosphorus is a metalloid which has higher melting point (about 600 C) than less metallic

190:

In German Knowledge (XXG) selenium is considered metalloid, but carbon and phosphorus are equated to fluorine and oxygen in metallicity (C and P are named as just nonmetals). Selenium is marked as half metalloid and half nonmetal in periodic table template in German Knowledge (XXG). Carbon and

5011:

This is of course just a statement of "tendencies". Given all the edge cases everywhere, I think it's a better approach than listing individual cases. It can be argued that C, As, Sb, and Bi are only forming quasi-metallic structures anyway, since the atoms are not equivalently positioned and

1238:

S and I are not that clear. By my reckoning, and for the following fifteen properties: first ionization energy; electron affinity; standard reduction potential; melting point; boiling point; liquid range; most stable oxidation state; ductility or malleability; appearance; Goldhammer-Herzfeld

5243:

I still feel that the topic should be defined before branching into specific examples or elements, which only confuses the layreader. At least move sentences two and three to the end, after the definition, but reading about a layer of fumes at the very beginning of the article is just odd.

4988:

Most nonmetals have biological, technological or domestic roles or uses. Living organisms are composed almost entirely of the nonmetals hydrogen, oxygen, carbon, and nitrogen. Near-universal uses for nonmetals are in medicine and pharmaceuticals; lasers and lighting; and household items.

1563:

Au and Pt are physically good metals, but chemically they are not good metals. (Typical) poor metals are low-melting, soft and have quite high electronegativity. Their chemistry is metalloidal in some way, even at low oxidation states. Group 12 elements also have domination of poor metal

1541:

Thank you. If we actually did something like this I wouldn't bother with the categories of polyatomic nonmetal and diatomic metal. There would only be the categories of near metalloid; typical nonmetal; and strong nonmetal. Au and Pt are not poor metals. They are nowhere near that: see

5694:

back in the day, I think, and it had similar problems to this. Is this an article about the concept of nonmetallicity? Or a survey of the various nonmetals and their chemical and physical properties? To what extent should we try to carry along the general reader into tricky ideas like

121:

The article says "Only eighteen elements in the periodic table are generally considered nonmetals, compared to over eighty metals, but nonmetals make up most of the crust, atmosphere and oceans of the earth. Bulk tissues of living organisms are composed almost entirely of nonmetals."

5084:

State of matter is slightly less irrelevant, because being a liquid/gas at r.t. usually means that a metallic state is thermodynamically unstable. Then again, it means that a large macromolecular structure is also thermodynamically unstable. And in any case this should be explained.

242:

Carbon high melting point and other not-nonmetallic traits in its allotropes does not make it more metallic than "diagonal boron group", but it should not be included in less metallic group than toxic and forming more acidic hydride than sulfur hydride element with atomic number 34.

2181:, some comments are made (also by me), so the current state of this article might not be fit for GAN. The issues are, IMO, about sub-classification of the nonmetals. Since this also involves the (abandoned?) enwiki 'categorisation' concept, it is wider than this article (and so at 3461:

I also has concerns at the comprehensiveness of the article. What are the enormous uses of the nonmetals? How does nonmetals are discovered since the ancient times? Why do the nonmetal criteria is so convoluted? How about bio-compatibility? There's much to discuss. (criterion 3a)

4455:, so can be interpreted as "a nonmetal is a chemical element that is typically a gas", which is both a vague and inaccurate description. I haven't modified anything myself because of all the discussions regarding the lead; further discussion and suggestions are welcome. Pinging 4400:

This is much better. I'm wondering if the final clause is even necessary in the lede sentence. Certainly the noble gasses are both low density and low strength. If that clause were placed later in the paragraph, you would avoid the "where applicable" language which seems a bit

1802:

The updated nonmetal article sets out the physical and chemical properties of the reactive nonmetals, and the noble gases, and by way of comparison, the metalloids. We think the transition in non-metallic properties, and the distinctiveness of each category, is well borne out.

1514:

changes color to brown-black. Plastic sulfur has low stability and it crystalizes to common, highly nonmetallic form. Hydrogen not always acts like a metal, it can acts like a metal and like a nonmetal. But hydrogen's chemical behavior is clearly strange for a typical nonmetal.

1519:

C, P and Se are "polyatomic near-metalloids" and I and H "diatomic near-metalloids". Compounds such as water or HF, HCl have also really relatively high boiling points when we compare their molar masses to their boiling points in Kelvin scale. Near-metalloids can be marked by

1232:

Don't call them semimetalloids, unless you can find some references in the literature supporting the use of that term. There are no sources in the literature that I know of that categorise these elements as semimetalloids. The closest there is is 'near metalloid' for C, P and

4285:"The hydrogen bond is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X–H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation." 4534:

you're busy, but appreciate you keeping an eye on things as you are able; few science-minded editors have the clarity of prose that you do, and I have No Clue when it comes to Chemistry! I kind of liked my attempt at the first paragraph of the lead, but what do I know :)

5727:. This would set out the scope of the article better e.g. plastics, woods and stones, all of which are "nonmetals" in a broad sense, are excluded. This problem doesn't arise with "metalloid" because of the strong association of that word with silicon and germanium etc. 5171:"Solid nonmetals, such as graphitic carbon and sulfur, are brittle to crumbly, and cannot be hammered into sheets or easily drawn into wires without shattering or breaking. Nonmetal atoms are moderate to high in electronegativity; they tend to easily attract electrons." 1952:

You're right about the source. It would nae be kosher. That aside, you would have to use the term "Highly electronegative nonmetal (noble gas)" to be accurate. You could add a note to the category label, and say noble gases have the highest EN values for their period.

5394:

While you all sort the ongoing issues with the definition in the lead, I will postpone my line-by-line at the peer review, where I had next planned to tackle clarity of prose. A good deal of progress has been made, but the article is yet a long ways from FAC ready.

1772:

While the current categories of polyatomic nonmetal (C, P, S, Se) and diatomic nonmetal (H, N, O, F, Cl, Br, I) are objective, being based on the structural motifs of the elements involved, the literature does not approach the chemistry of the nonmetals in this way.

5115:. But for the first sentence of the lead here, it says nothing except a nonmetal is not a metal, which is not entirely helpful for what will be coughed up by Google. It could benefit from one more clause that gives a "such as" overview of the mentioned properties. 4511:

I didn't have the PR on my watchlist, so I don't think I saw your suggestion until just now. My thoughts are pretty much the same as yours: a broad statement qualifying what a nonmetal is. Should I copy-paste this comment to that page to keep the discussion in one

2008:, an IP changed from "odourless" to "odorless". I looked and don't see an ENGVAR template, so maybe you can have a look and see if the national variety has been established and if so, place the appropriate template and either sustain or revert this edit. Ta! 4846:

That just leaves the shiny nonmetals C, P, Se and I; and the part-time nonmetals err metalloids B, Si, Ge, As, Sb, Te. There are no poor conductors here: C, As, Sb are metallic conductors; the rest are semiconductors consistent with their shiny appearance.

2300:(2) the categorisation (classification) metal–metalloid–nonmetals was never dropped nor disputed. That includes their coloring (which is what this is about): still around. Also, the coloring for noble gases and halogens is still in use (even in this image). 3331:

I’ve abandoned the idea of defying nonmetals in terms of what they are. Picking up on Double sharp’s suggestion, and SG’s comment, the lede paragraph now reads:

This is an impractical basis for an element categorisation scheme since it would give us a total of 14 colour categories, including metals, and the metalloids.

804:"Chemically, the nonmetals have relatively high ionisation energy and high electronegativity;" - should ionisation energy and electronegativity be pluralised? 2689:

The article on metals makes a distinction between the physics and chemistry. Should something similar be done here. Or is the term nonmetal purely chemistry?

4306:"A nonmetal is a relatively light chemical element that is mechanically weak, and that forms an acid or an oxide if it reacts with nitric acid." (26 words) 4767:

I intend to shortly post some thoughts on the background to the evolution of the lede. For now, please note that I’ve further refined the lede paragraph.

I agree that the current led sentence is problematic for all the reasons you have mentioned. Exacerbating this is the presence of the word "typically".

Virtually all elements, to varying degrees, have a mixture of metallic and nonmetallic properties. Only a few have such a mixture to a marked extent.

The rest of the nonmetals are nearly all gases at room temperature (the only liquid nonmetal, bromine, is usually topped by a layer of its own fumes).

I'm not sure if "mechanically" is quite the right term since the intending meaning is that nonmetals (normally) have no structural strength.

Thanks YBG. I appreciate your interest and taking the time to post your concerns. I note you concur that a positive definition is preferred.

metals discovered from then until 1809 had relatively high densities; their heaviness was regarded as a singularly distinguishing criterion.

Nonmetal atoms are moderately to highly electronegative; they tend to attract electrons in chemical reactions and to form acidic compounds.
