No258,260[edit]

If you check out the isotopes of Mendelevium, it can be seen that Md258,260 have a non-negligible chance of decaying into No258,260. 32ieww (talk) 22:53, 11 February 2017 (UTC)[reply]

Yes, they do. Are you suggesting any changes to the article? Double sharp (talk) 03:09, 12 February 2017 (UTC)[reply]

Reaction with ammonia[edit]

I believe nobelium metal behaves similarly to ytterbium metal and the alkaline earth metals, dissolving in ammonia to form blue electride salts. Sometimes Mendelevium may also be able to form electride salts. Anoop Manakkalath (talk) 22:49, 7 December 2022 (UTC)[reply]

If you're proposing this as an addition to the article, do you have a source for verification? Nobelium (and mendelevium) cannot be produced in macroscopic quantities, so I don't see how the formation of blue electride salts could be discerned. ^Complex/_Rational 05:10, 8 December 2022 (UTC)[reply]

Based on periodicity I agree that this is likely for nobelium (Cm-No seem quite similar to La-Eu), but without a source it does not belong in the article. Double sharp (talk) 14:54, 9 December 2022 (UTC)[reply]
