Accidents and incidents occur all the time. While their scale and magnitude may merit inclusion in Knowledge (XXG) on grounds of notability, that such an accident has occurred is not sufficient justification for inclusion in the context of an article about chemicals.

Claims and statements in articles should mainly be supported by references to textbooks, monographs, and related book series. In many cases, especially for historic purposes, the primary literature (journals) are used. Intermediate between journal articles, which are often highly specialized, and

In general, descriptions of chemical knowledge do not mention who did the work or where the discoveries were made, in part because such information is available in the citations. This approach simplifies the presentation and helps readers focus on facts and explanations. The obvious exceptions to

Systematic nomenclature, while being precise, can be cumbersome. Commonly accepted trivial or alternative names are preferred over systematic names. In particular, IUPAC recommends the use of non-systematic names for some organic compounds, and these recommendations should be followed in article

Although many organometallic reagents have complex structures involving solvation or clusters, these reagents are ordinarily depicted in simplified structures (RMgX with two-coordinate Mg, BuLi with one-coordinate Li, etc.). To facilitate sharing of drawings between different language wikis,

Journalism. Knowledge (XXG) should not offer first-hand news reports on breaking stories. Knowledge (XXG) is not a primary source. However, our sister project Wikinews does exactly that, and is intended to be a primary source. Knowledge (XXG) does have many encyclopedia articles on topics of

Descriptions of hazards should, as far as possible, be based on published, peer-reviewed sources (which should, of course, be cited at the appropriate point in the article). A list of resources for chemical safety information is given in the external links section of these guidelines.
1648:) Historic accidents and incidents may only be contextualized in the discussion on the specific hazards of certain chemicals, without serving as case studies in itself. To reiterate, if such accidents are sufficiently notable, they should have their own article (e.g. discussion in 1049:(IUPAC) provides recommendations and definitions for nomenclature and terminology. Knowledge (XXG) editors strive to be mindful of IUPAC's advice but do not follow this advice rigidly, especially when the advice deviates from mainstream usage (see comments below on nomenclature). 1488: 1437:
Images of chemical compounds or their solutions are useful to readers. Most useful are colored compounds but even colorless/white samples/solutions can be useful. The provenance of these images is however impossible to verify. The following images provide some guidance.

Preparation. It is our tradition to cite the first preparation of a compound. For commercially important compounds, it is often useful to distinguish reactions used in industrial production separately from "laboratory routes". For natural products, the biosynthesis is

They confuse readers trying to understand basics, since stoichiometry is conflated with phase information. 1016:. Important topics include compounds, reactions, methods of analysis, instrumentation/apparatus, techniques, significant chemists, branches of chemistry, chemical theories, and principles which have received significant coverage in independent reliable sources. 1584:

Where a compound class does not have sufficient detail to merit a full article, it should be merged to the parent article (usually that of the acid). Articles named after a parent compound should generally appear at the plural of the parent compound.

Structure. The structures of many organic compounds are obvious, but inorganic and metal-containing compounds often adopt nonintuitive structures. When possible, their structures should be described, ideally based on crystallographic or related

reagents above and below arrows should consist of formulas, not words. Experimental conditions are ordinarily omitted from equations. The prose can comment on conditions, yields, and other details. Equations are ordinarily not numbered.

Isotopes should be labelled by their mass number, e.g. C and F. Deuterium (H) and tritium (H) may be labelled "D" (or "D") and "T" (or "T"), respectively. Deuterated solvents for NMR use are customarily described variously as:

Articles are placed in one or more categories to help readers and editors locate similar topics. When categories become too large to be readily searched, it is common to create subcategories. For example,

This section should include a broad description of the reaction in both text and reaction scheme. References to review articles are preferred. References to the discovery of the reaction is also welcome.
2617: 2612: 542: 532: 1123:, the type of English used to write an article does not matter, but it should be consistent. The following exceptions apply for chemical names, when the article itself is primarily about chemistry: 1516: 2187: 2672: 1472: 592: 2832: 2759: 2687: 2570: 1375: 941: 768: 677: 607: 478: 2804: 2739: 2682: 2637: 1807: 926: 733: 657: 602: 557: 2729: 2667: 2657: 694: 587: 582: 1618:

The description of hazards should avoid hyperbole. The role of Knowledge (XXG) is to give balanced and accurate information, to allow its readers to reach their own conclusions.
