Seaborgium: the essentials

Seaborgium is a synthetic element that is not present in the environment at all. It has no uses.

Table: basic information about and classifications of seaborgium.

Seaborgium: historical information

Seaborgium was discovered by Albert Ghiorso and others at 1974 in 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..

Transuranium elements such as seaborgium can be created artificially in particle accelerators. Isotopes of seaborgium have short half-lives of less than a second. The first report of element 106 came in 1974 from the Soviet Joint Institute for Nuclear Research and these were followed later by others from Berkeley in California, USA. Experiments at the same American institution confirmed the discovery in 1993. The Russian experiments involved the bombardment of lead isotopes with high energy 54Cr ions while the American results followed the collision of 18O ions with 249Cf ions.

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
