Seaborgium is a synthetic element with the chemical symbol Sg and atomic number 106. It was first discovered in 1974 by a team of scientists at the Lawrence Berkeley National Laboratory in California. Seaborgium is part of the transactinide series and is classified as a transition metal. Due to its instability, it has no significant commercial applications and is primarily used for research purposes. Seaborgium is named after the American chemist Glenn T. Seaborg, who contributed significantly to the discovery of several heavy elements. It is produced in particle accelerators through nuclear reactions, typically by bombarding californium with oxygen ions. The most stable isotope, Sg-271, has a half-life of about 2.5 minutes.
