Seaborgium: properties of free atoms

Seaborgium atoms have 106 electrons and the shell structure is  2.8.18.32.32.12.2.

The ground state electron configuration of ground state gaseous neutral seaborgium is  [Rn].5f14.6d4.7s2 (a guess based upon that of tungsten) and the term symbol is  5D0 (a guess based upon guessed electronic structure).

Electron binding energies

Electron binding energies for seaborgium. All values of electron binding energies are given in eV. The binding energies are quoted relative to the vacuum level for rare gases and H2, N2, O2, F2, and Cl2 molecules; relative to the Fermi level for metals; and relative to the top of the valence band for semiconductors.
