Seaborgium: the essentials
Seaborgium atoms have 106 electrons and the shell structure is 18.104.22.168.32.12.2. The ground state electronic configuration of neutral seaborgium is [Rn].5f14.6d4.7s2 (a guess based upon that of tungsten) and the term symbol of seaborgium is 5D0 (a guess based upon guessed electronic structure).
Seaborgium is a synthetic element that is not present in the environment at all. It has no uses.

Seaborgium: historySeaborgium was discovered by Albert Ghiorso and others in 1974 at The Lawrence Berkeley Laboratory in California and the Livermore National Laboratory, USA.. Origin of name: glenn T. "Seaborg", American nuclear chemist and Nobel prize winner..
Isolation: only very small amounts of of element 106, seaborgium, have ever been made. The first samples were made through a nuclear reaction involving fusion of an isotope of californium, 249Cf, with one of oxygen, 18O.
18O + 249Cf → 263106Sg + 4 1n
Isolation of an observable quantity of seaborgium has never been achieved.
More recently, other isotopes have been made at the Paul Scherrer Institute (PSI) in Switzerland using neon atoms to bombard californium isotopes.
248Cf + 22Ne → 266Sg + 41n
