Nobelium Bohr ModelNobelium is a Block F, Group 3, Period 7 element. The number of electrons in each of nobelium's shells is 2, 8, 18, 32, 32, 8, 2 and its electron configuration is [Rn] 5f14 7s2. The nobelium atom has a Van der Waals radius is 246.pm. In its elemental form, nobelium's CAS number is 10028-14-5. Nobelium is radioactive and its appearance is unknown. It was discovered by Nobel Institute of Physics in Stockholm and later by Albert Ghiorso, Torbjorn Sikkeland, J. R. Walton and Glenn T. Seaborg  in 1958. The element was named in honor of Alfred Nobel, the inventor of dynamite.
