Predictions on the aqueous chemistry of seaborgium have largely been confirmed. His legacy was cemented with the naming of element 106 as seaborgium in his honor. The Americans also wished to name element 106 seaborgium. The transactinide seaborgium is named in his honor. The transactinide seaborgium was named in his honor. Seaborgium (Sg) is a synthetic element and so has no stable isotopes. Isotopes of seaborgium have also been observed in the decay of heavier elements. Thus, IUPAC reconsidered, and in 1996 named element 105 dubnium and element 106 seaborgium. In the 1970s he claimed as his discovery two transition metal elements&colon; seaborgium and bohrium. The synthesis of seaborgium was first realized in 1974 by the LBNL/LLNL team. Seaborgium has no stable or naturally occurring isotopes. Seaborgium is a synthetic chemical element with the symbol Sg and atomic number 106. Seaborgium is the first element ever to have been officially named after a living person.
