 In this region of the periodic table, "N" = 184, "N" = 196, and "N" = 228 have been suggested as closed neutron shells.Therefore, the isotopes of most interest are 310126, 322126, and 354126, for these might be considerably longer-lived than other isotopes.Element 126, having a magic number of protons, is predicted to be more stable than other elements in this region, and may have nuclear isomers with very long half-lives.
