NobeliumIn 1957, an announcement was made of the discovery of element 102, and the name of nobelium proposed, for an isotope believed found with a half-life of 10 minutes at 8.5 MeV. Later tests showed that no isotopes of nobelium have this half-life. Nobelium was truly discovered by Albert Ghiorso, T. Sikkeland, J.R. Walton, and Glenn T. Seaborg in Apr 1958. However, IUPAC accepted the name Nobelium given to the prematurely discovered element. Ten isotopes of nobelium are known to exist, with No-255 having the longest half-life of 3 minutes. Nobelium is an artificially made, radioactive, “rare earth metal”named after Alfred Nobel who discovered dynamite. |
