Seaborgium

Seaborgium (pronounced /siːˈbɔrɡiəm/ ( listen), see-BOR-gee-əm) is a 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. The Berkeley team suggested the name seaborgium (Sg) to honor the American chemist Glenn T.

Seaborgium (pronounced /siːˈbɔrɡiəm/ ( listen), see-BOR-gee-əm) is a 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. The Berkeley team suggested the name seaborgium (Sg) to honor the American chemist Glenn T. Seaborg credited as a member of the American group in recognition of his participation in the discovery of several other actinides. The name selected by the team became controversial. The IUPAC adopted unnilhexium (symbol Unh) as a temporary, systematic element name. In 1994 a committee of IUPAC recommended that element 106 be named rutherfordium and adopted a rule that no element can be named after a living person. This ruling was fiercely objected to by the American Chemical Society. Critics pointed out that a precedent had been set in the naming of einsteinium during... less
