evidence" to suggest it is the end, and the second says "the nuclear shell of element 126 might confer some relative stability on neighbouring elements so that possibly 127 and 128 might exist, but this latter one (unbioctium) would probably mark the end of the periodic table." That's all it says, not sure if it's reliable enough to add, unless you go by the fact that the book is more recent than most other publications.

312:"Since the relatively long-lived isotope plutonium-240 occurs in the decay chain of plutonium-244 it should also be present, albeit 10,000 times rarer still. Finally, exceedingly small amounts of plutonium-238, attributed to the incredibly rare double beta decay of uranium-238, have been found in natural uranium samples."

Unfortunately, the paragraph is not very detailed. It doesn't cite any source (the whole book doesn't either; it just has a massive bibliography at the back in a random order), and is the information on the last element is in only two sentences of this paragraph. The first just says there is "growing

Previously the article didn't list the natural isotopes, but now it does. (Would it be too much to ask for a complete list of all isotopes listed as natural in the book? It would really help update many of the isotope pages with new information and would finalize all the changes to

we give 173 as the highest possible element. 137 was formerly thought to be the highest (using the Bohr model or even the "classical" atomic structure), but detailed quantum theoretical investigation raises the limit to 173. Anyway, I think the 128 claim is noteworthy to add.
601:
Yeah, that's probably the best way to add it to the article. I'm not sure if it's 100% fact, but it is verifiable. Other than that, I'll add all the relavant information about the unnamed elements to the respective articles tomorrow, and I think all that leaves in the

Yes, sorry, it was 173. But maybe it is worth a mention as the source is quite recent. Additionally, I will get around to filling in those details as promised above, I've just been a bit busy recently with studies.

The book only lists four (215, 217-219) which it seems the article already lists. The book simply states what the isotopes are, and no reactions are given, so I'm afraid I can't help you there :(

That site has been very useful in helping us with the last few images, and I have uploaded some images from there. Unfortunately, it does not give any images of pure Pm, At or Ac.

Also, Walter
Greiner claims that there is no end to the periodic table. An infinite number of elements seems unlikely(!), but it seems as though 173 is not actually a limit (see
