Nobelium

Description

 

Nobelium, a radioactive, metallic chemical element. Nobelium does not occur in nature; it is produced artificially in trace amounts in cyclotrons and linear accelerators.Nobelium was discovered in 1958 by Albert Ghiorso, Glenn T. Seaborg, Torbjrn Sikkeland, and John R. Walton at the University of California, Berkeley. Nobelium is normally a divalent ion in aqueous solution.Nobelium can be produced by irradiating a californium-249 target with carbon-12 ions.
