The article on Erbium the section on Isotopes uses NUBASE2020 as its sole reference. Then it makes statements like:
However, the NUBASE reference contains nothing but tables of isotope properties. It seems to me that we could cite the table for facts about specific isotopes, but nothing about the collection of them. That is, the entire isotopes section is original research based on analyzing the tables. Since this is a template reference it seem like the use may be widespread. What do you think?

I cropped a few of the gas discharge tube images to make it more clear which part was the noble gas (specifically krypton, argon, and xenon are currently cropped) but this has been contested by @Zzzs (pinging here), so I'm putting up a talk page section.
They are featured pictures, but it's still a featured picture if you crop to the important bit for ease of understanding & comparison. Mrfoogles (talk) 18:49, 19 July 2024 (UTC)
Zirconium has been nominated for a good article reassessment. If you are interested in the discussion, please participate by adding your comments to the reassessment page. If concerns are not addressed during the review period, the good article status may be removed from the article. Z1720 (talk) 00:14, 23 July 2024 (UTC)
Should this content on the discovery of the 23 nonmetals be removed from the nonmetal article?
RfC is here. --- Sandbh (talk) 13:37, 23 July 2024 (UTC)
The infobox image for neptunium was recently replaced by File:Neptunium_metal.jpg because the old image didn't show the pure metal. It will need to be reassessed for Wikipedia:WikiProject_Elements/Pictures. –LaundryPizza03 (dc̄) 00:47, 4 August 2024 (UTC)
@Grendon84 has been systematically changing the first part of elements like:
to remove "the":
The edits are marked minor and have no edit summary.
If there is an agreed form this it should be cited in the change. If not these changes should not be made, they are just annoying and to me they read like a word is missing. Johnjbarton (talk) 16:57, 9 August 2024 (UTC)
While cleaning Isotopes of silver (updated to NUBASE2020 in 2022), I uncovered a paper, which has been accepted to Physical Review C and is available as an arXiv preprint, that updates the masses of various nuclei.
This updates the following nuclei and their isomers: 84Br, 105Mo, 115Pd, 119Pd, 121Pd, 122Ag, 127In, 129In, and 132Sb. In particular, I have updated 122Ag in the table — for this nucleus, the 3− state in NUBASE2020 is declared nonexistent. –LaundryPizza03 (dc̄) 07:05, 2 September 2024 (UTC)
Of the known elements, we know for certain what ninety-seven look like at STP (the first ninety-nine less astatine and francium).
It's predicted that astatine is silvery metallic, and I assume francium would be the same. But I'm not sure if relativistic effects kick in - caesium is a bit golden - why shouldn't francium be, or is francium likely silvery as well? I'm not sure. Wikipedia does not make any assumptions to what francium's color might be in its article. Silvery like most? Or golden like caesium?
I presume fermium onwards are all likely silvery, I note Wikipedia says roentgenium is likely silvery, so I assume that all past fermium are at least to tennessine, maybe oganesson? I'm not sure what oganesson would probably look like if it's not a gas, as Wikipedia says it's probably a solid.
Is there any data on what these elusive radioactive elements might look like if we were to theoretically get a macroscopic sample of them and have the result not be instant destruction and death? 108.160.120.147 (talk) 18:12, 2 September 2024 (UTC)
