Half-Life

The most stable known isotope, meitnerium-278, has a half-life of 7.6 seconds

Except if you look at the table of isotopes in the article, then it is 4 seconds. Or in the German wikipedia, then it is 30 minutes (although they state meitnerium-276 is the most stable isotope). https://de.wikipedia.org/wiki/Meitnerium https://de.wikipedia.org/wiki/Liste_der_Isotope/7._Periode#109_Meitnerium 77.182.66.75 (talk) 17:17, 28 August 2018 (UTC)

The half-lives up in this region of the nuclide chart are not known very well. I will look and see which is the latest value, but it may change significantly in the future. Double sharp (talk) 00:03, 29 August 2018 (UTC)

Compounds

Is MtF6 a Compound?Porygon-Z 21:17, 10 March 2019 (UTC) — Preceding unsigned comment added by Porygon-Z474 (talk • contribs)

It would be, but it hasn't yet been synthesised. Double sharp (talk) 03:21, 11 March 2019 (UTC)

OK, It's just all too confusing with the "should be, could be, and would be." Porygon-Z 13:42, 28 March 2019 (UTC) — Preceding unsigned comment added by Porygon-Z474 (talk • contribs)

Atomic mass of 268 or 278?

File:Periodic table large.svg presents a atomic mass of (268), but the current version of this article says (278). Is the File incorrect? Mateussf (talk) 13:54, 19 June 2024 (UTC)

The file is outdated. Based on current data, the most stable known isotope is unambiguously ²⁷⁸Mt. Values are similarly incorrect for several other superheavy elements. ^Complex/_Rational 15:06, 19 June 2024 (UTC)
