Binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and other compounds of seaborgium where known.
Seaborgium wasdiscovered 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 + 41n
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.
