Not done: Seaborg and Perlman found plutonium in nature in 1942, but it was synthesized in 1941, which I suspect is why Perlman isn't generally listed as a discoverer. PianoDan (talk) 17:03, 15 November 2024 (UTC)Reply
empirical atomic radius
Latest comment: 5 months ago3 comments2 people in discussion
Plutonium's empirical atomic radius is often listed as 175 pm, but on this article, it is 159 pm. Which is strange, since I swear it was previously 158 pm. Where are the measurements coming from? Why are there never sources linked to empirical atomic radii? GracefulFern3145 (talk) 19:00, 6 March 2026 (UTC)Reply
The empirical atomic radius listed for plutonium on the article is 175 pm, so where is 158/159 pm coming from? Also, the source for that claim is from 1964. Aren't old sources not recommended? It's probably the only one of its kind, but it is still from 1964. GracefulFern3145 (talk) 15:49, 10 March 2026 (UTC)Reply
Change oxidation states in infobox
Latest comment: 2 months ago1 comment1 person in discussion
I propose the common oxidation states in the infobox be changed to +3, +4, +5, and +6. Please read the discussion here.
