Nobelium: the essentials
Nobelium atoms have 102 electrons and the shell structure is 188.8.131.52.32.8.2. The ground state electronic configuration of neutral nobelium is [Rn].5f14.7s2 and the term symbol of nobelium is 1S0.
Nobelium is a radioactive "rare earth metal" named after Alfred Nobel who discovered dynamite.
