Nonmetal article mini-property tables

Colleagues, I would appreciated your thoughts concerning the Nonmetal article, and the discussion at the talk page regarding the mini-physical properties table and the mini-chemical properties table, here: Talk:Nonmetal#Delete_the_two_short_"general_properties"_tables Sandbh (talk) 13:05, 14 July 2026 (UTC)

Element infoboxes nominated for replacement with Infobox element

Please see this discussion. – Jonesey95 (talk) 23:23, 17 July 2026 (UTC)

NUBASE2020

As far as I can tell all Elements have (at least) two copies of

• Kondev, F. G.; Wang, M.; Huang, W. J.; Naimi, S.; Audi, G. (2021). "The NUBASE2020 evaluation of nuclear properties" (PDF). Chinese Physics C. 45 (3) 030001. doi:10.1088/1674-1137/abddae.

That is because they say

• :''All nuclear data not otherwise stated is from the standard source:<ref>{{NUBASE2020}}</ref>''

and also include {{Infobox isotopes (meta)}}. Tried

• :''All nuclear data not otherwise stated is from the standard source:<ref>{{NUBASE2020|name}</ref>''

but then it is undefined. Johnjbarton (talk) 00:00, 28 July 2026 (UTC)

Sg — atomic weight?

The Periodic table article with the big table and the Seaborgium article disagree. ~2026-42620-64 (talk) 08:45, 2 August 2026 (UTC)

It's either 267 of 269. There is a footnote explaining the reason its atomic weight is unclear at Seaborgium. -- Reconrabbit (talk) 13:26, 4 August 2026 (UTC)

Why is the half-life of ²⁶⁹Sg listed as 13 minutes in the isotope table but as 5 ± 2 minutes in the footnote there?

User:248Cm-Target changed it in June 2025 based on a powerpoint presentation that tangentially had a diagram of superheavy element half-lives (and it didn't even match the reference then). -- Reconrabbit (talk) 14:27, 4 August 2026 (UTC)
