Discuss There are three identified isotopes of smith broule having masses of 313967 amu 3124 amu and 314632 amu respectively?

Answer 1

The highest isotope mass known to me is 263.118 amu for element 106Unh, so never reaching the 300000 or 3000.

Further looking with an inserted decimal point reveales only:

15P(32) = 31.97391 amu

and 16S(32) = 31.97207 amu
