Seaborgium

seaborgio

Seaborgium atoms split in about three minutes, so very little is known about it. Scientists think it may be a metal. The element was isolated in 1974, in a superheavy ion linear accelerator at Lawrence Berkeley National Laboratory. It was named after U.S. Nobel laureate Glenn T. Seaborg.
