Seaborgium is a synthetic chemical element named after American nuclear chemist Glenn T. Seaborg.
Core Principles & Analysis
Seaborgium was synthesized in 1974 at Berkeley by bombarding californium-249 with oxygen-18 ions; a competing Dubna claim from the same year was later judged inconclusive.
Its 1997 naming for Glenn Seaborg broke precedent as the first element officially named after a living person, adopted over initial IUPAC objections.
In 2014 researchers synthesized seaborgium hexacarbonyl, Sg(CO)6, the first carbonyl complex of a superheavy element, showing seaborgium bonds like its group-6 homologs molybdenum and tungsten.
