Plutonium Bohr ModelPlutonium is a Block F, Group 3, Period 7 element. The number of electrons in each of Plutonium's shells is 2, 8, 18, 32, 24, 8, 2 and its electronic configuration is [Rn] 5f6 7s2. In its elemental form, CAS 7440-07-5, plutonium has a silvery white appearance. The plutonium atom has a radius of and it's Van der Waals radius is Plutonium is found in some concentrated ores of uranium. Plutonium was discovered by Glenn T. Seaborg, Edwin M. McMillan, J. W. Kennedy and A. C. Wahl  in 1940. The element Plutonium was named after the planet Pluto.
