Nobelium is a radio active atom that was obtained by nuclear fusion techniques. It does not occur in nature.

What the name means: Nobelium was named after the Swedish chemist, Alfred Nobel .
The International Union of Pure and Applied Chemistry (IUPAC)  temporarily named the new element Unnilbium, with the symbol Unb. In 1997 the IUPAC approved the name nobelium, symbol No.

Who made nobelium?: There was some argument about which group of researchers were the fist to produce nobelium. Two American groups and a Russian group claimed to have done so first. The achievement was eventually attributed to Albert Ghiorso, Glenn Theodore Seaborg and their co-workers at the Berkeley Laboratory of the University of California, USA in 1958.
