Thorium in periodic table
A thorium atom has 90 electrons, of which four are valence electrons. Four atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, 7s, and 7p. Despite thorium's position in the f-block of the periodic table, it has an anomalous [Rn]6d 7s electron configuration in the ground state, as the 5f and 6d subshells in the early actinides are very close in energy, even more so t… WebNeutrons: 142. Shell structure: 2,8,18,32,18,10,2. Electron configuration: [Rn]6d27s2. Oxidation state: 4. Crystal structure: cubic face centered. Named after Thor, a Scandinavian god of war, thorium is about three times more abundant than uranium. It is found in small amounts in rocks and soils, with abundant supplies in several countries.
