Beryllium-8 natural occurrence

Shouldn't beryllium-8 be listed as "intermediate " rather than "synthetic", since it's in secular equilibrium in helium fusing stars such as the sun? 174.103.211.189 (talk) 04:16, 7 December 2023 (UTC)[reply]

GA concerns

I am concerned that this article no longer meets the good article criteria due to several uncited statements, including entire paragraphs. Is anyone interested in addressing this concern, or should this go to WP:GAR? Z1720 (talk) 03:25, 14 January 2025 (UTC)[reply]

The article contains uncited statements, some tagged with "citation needed" since 2023. Z1720 (talk) 23:29, 23 January 2025 (UTC)[reply]

This looks like an easy "save". There are a lot of citations. One area that is weak is isotopes, may be @Double sharp or @Nucleus hydro elemon knows sources?

I Looked in to the two citation needed and simply deleted the sentences as unsourced and not notable. Johnjbarton (talk) 02:09, 24 January 2025 (UTC)[reply]

@Johnjbarton: I added cn tags to the places where I think citations are needed. Z1720 (talk) 02:20, 24 January 2025 (UTC)[reply]

...beryllium is, uniquely among all stable elements with an even atomic number, a monoisotopic and mononuclidic element. I'm not sure is CIAAW enough to cite this. It verifies that beryllium is the only monoisotopic element with an even atomic number, but not the only mononuclidic element with an even atomic number. If we list all 21 mononuclidic elements, we can see that beryllium is the only one with an even atomic number, but I'm not sure is that allowed.
The shortest-lived known isotope of beryllium is ¹⁶Be, which decays through neutron emission with a half-life of 6.5×10⁻²² s. Is it notable? Even it is, as the half-lives of ¹⁵Be and ¹⁶Be are 790±270 ys and 650±130 ys, there should be a footnote as in the article technetium to explain why the shortest-lived known isotope cannot be determined based on existing data. It is quite a trouble to me.
No beryllium silicide has been identified. I can't verify this. Perhaps it appears somewhere else where I missed, or it adds another [citation needed] into the article.
Although Wöhler first used to term "beryllium" in 1828, it is not the first word derived from beryl. The names "beryllina", "beryllerde", "berylline" (all from doi:10.1007/s10698-022-09448-5) were used before "beryllium", and perhaps should be mentioned in the article.

I have some answers (?) to the first and third bullet points.

It's fairly difficult to find reliable sources that compare the elements in regards to arbitrary characteristics like this, but comparing data in a table like Atomic Weights and Isotopic Compositions probably falls under WP:CALC.
Beryllium silicide (in the form of nanoclusters) is the subject of a few density functional theory studies (doi:10.48550/arXiv.1205.5931, doi:10.1016/j.cplett.2012.04.002) and appears to have been created at least once in real life (doi:10.1016/S0009-2614(02)01637-8), so I would say that "no beryllium silicide has been identified" is incorrect now.
