A +1 oxidation state?

https://www.nature.com/articles/s41586-020-2299-4 Should I add the +1 oxidation state to the infobox for this article? It seems reasonable, since the radium in RaF gave away one electron to a fluorine. SupercriticalXenon (talk) 14:41, 25 May 2024 (UTC)[reply]

Physics beyond the standard model

Is the information in the article under Modern applications regarding radium's place in "new models" of physics due to breaking forces useful? It seems overly technical in relation to the rest of the article and the sources provided don't make much mention of radium in particular. Could be some kind of WP:SYNTH?

Glaring error

"In the early history of the study of radioactivity, the different natural isotopes of radium were given different names..."

No, they were not - there was no way to separate them at that time.

Someone please fix this. The most effectual Bob Cat (talk) 13:24, 24 August 2024 (UTC)[reply]

I think you are assuming someone had a mixture of the different isotopes in a sample they knew to be the "same chemical element" and then separated them into the various isotopes. Instead, different isotopes come from different sources based on being products of different elements' decay-chains. And the isotopes might have different properties, such as different radioactivity. If I start with X and get Y that then has behavior Z and you start with A and get B that has behavior C, we might not know at first that Y and B are the same element. Thus there were substances known as "Actinium X", "Thorium X", and "Mesothorium 1" that turned out to be radium-233, 234, and 238, respectively. DMacks (talk) 17:08, 24 August 2024 (UTC)[reply]
