Quick answerSeaborgium (Sg) is a transition metal with atomic number 106 and a mass number of 269 (the most stable isotope), in group 6, period 7. It was discovered by Albert Ghiorso and colleagues in 1974. It is used for superheavy element research and studying transactinide chemistry. Its electron configuration is [Rn] 5f14 6d4 7s2 (predicted).
Seaborgium is a synthetic element named for Glenn Seaborg while he was still alive, a rare honour.
