Element 106 Named for University of California Chemistry Professor

March 15, 1994

SAN DIEGO (AP) _ The 106th element in the periodic table has been named ″seaborgium″ in honor of Nobel laureate Glenn T. Seaborg, a University of California chemistry professor.

Seaborg is the co-discoverer of plutonium and nine other transuranium elements, which come after uranium on the periodic table and are artificially created in particle accelerators.

The announcement of the name seaborgium, identified by the chemical symbol Sg, came from the element’s co-discoverer, Kenneth Hulet, a retired chemist from the Lawrence Livermore National Laboratory. Hulet made the announcement Sunday at an American Chemical Society’s annual meeting.

Seaborg is associate director-at-large for the Lawrence Berkeley Laboratory. For discovering plutonium, Seaborg shared the 1951 Nobel prize for chemistry with former LBL director Edwin MacMillan.

Seaborg was chairman of the Atomic Energy Commission, now the Nuclear Regulatory Commission, from 1961 to 1971.

Seaborgium’s discovery was confirmed last summer.
