A small part of the super-HILAC under construction at the Berkeley Lab in 1972. In 1974, seaborgium atoms were synthesized in this accelerator.
Discovery of Seaborgium
Seaborgium was first synthesized in 1974 at the Lawrence-Berkeley Laboratory, USA, by a team of scientists led by Albert Ghiorso and at the Joint Institute for Nuclear Research at Dubna, Russia.
The element was named after Nobel prize winner Glenn Theodore Seaborg, the American nuclear chemist.
Appearance and Characteristics
Harmful effects:
Seaborgium is harmful due to its radioactivity.
Characteristics:
Seaborgium is a radioactive synthetic metal and has only been produced in tiny amounts.
Uses of Seaborgium
Seaborgium is of research interest only.
Abundance and Isotopes
Abundance earth’s crust: nil
Abundance solar system: nil
Cost, pure: $ per 100g
Cost, bulk: $ per 100g
Source: Seaborgium is a synthetic, radioactive metal, created by nuclear bombardment. It has only been produced in tiny amounts. The metal is made by bombarding californium-249 with heavy oxygen ions.
Isotopes: Seaborgium has 11 isotopes whose half-lives are known, with mass numbers from 258 to 271. None are stable. The most stable isotope is 271Sg with a half-life of 1.9 minutes.
