Seaborgium (/siːˈbɔrɡiəm/ see-BOR-gee-əm) is a synthetic chemical element with the symbol Sg and atomic number 106.
Seaborgium is a synthetic element whose most stable isotope Sg has a half-life of 1.9 minutes. A new isotope Sg has a potentially slightly longer half-life (ca. 2.1 min) based on the observation of a single decay. Chemistry experiments with seaborgium have firmly placed it in group 6 as a heavier homologue to tungsten.

Seaborgium (/siːˈbɔrɡiəm/ see-BOR-gee-əm) is a synthetic chemical element with the symbol Sg and atomic number 106.
Seaborgium is a synthetic element whose most stable isotope Sg has a half-life of 1.9 minutes.

Chemistry experiments with seaborgium have firmly placed it in group 6 as a heavier homologue to tungsten.
Element 106, now known as seaborgium, was first created in 1974 at the Super HILAC accelerator at the Lawrence Berkeley Laboratory by a joint Lawrence Berkeley/Lawrence Livermore collaboration led by Albert Ghiorso and E. Kenneth Hulet. They produced the new nuclide Sg by bombarding a target of Cf with O ions. This nuclide decays by α emission with a half-life of 0.9 ± 0.2 sec.
The Berkeley/Livermore collaboration suggested the name seaborgium (Sg) to honor the American chemist Glenn T. Seaborg credited as a member of the American group in recognition of...
