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.

Seaborgium is radioactive.

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.
