[edit] Atomic Mass
It seems odd that the atomic mass is 268, but the only mentioned isotope is 276 ... in general, 268 seems light. Perhaps there is an error in the infobox? Stifynsemons 03:38, 8 January 2007 (UTC)
- Why should infoboxes list atomic masses at all for synthetic elements? If you look at Isotopes of meitnerium, both 268 and 276 (and a few others) are known. Kingdon 04:46, 5 March 2007 (UTC)
- acccording the infobox list they have used the atomic mass for the most stable isotope, and its used (268) there. Why is 276 used here? —The preceding unsigned comment was added by Grrahnbahr (talk • contribs).
- You're right - Atomic mass says the most stable. But in this case (see Isotopes of meitnerium), the most stable based on theoretical predictions is 278 and the most stable based on experimental data (of those which have been measured, of course) is 276. I've been picking the latter; someone else seems to have picked the former. I don't see 268 anywhere. Kingdon 02:16, 11 June 2007 (UTC)
