Properties of seaborgium Seaborgium is a synthetic element about which little is known. It is presumed to be a solid metal, but since only a few atoms of it have been created, it is difficult to study. read more
Seaborgium-263 is an isotope of seaborgium with a half-life of about 1 second. Three months before the Berkeley group announced their discovery, a team of scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, claimed to have produced seaborgium. read more
