Nobelium is an artificial chemical element, radioactive and unstable.

Nobelium was first and surely prepared in 1966 by Russian physicists from Dubna; another claim from American physicists (1958) was not accepted by IUPAC.

Nobelium was obtained using this nuclear reaction:

238 92U + 2210Ne → 260102No* → 254102No + 6 10n
