Chemical Elements.com - Thorium (Th)
Th is an isotope of thorium with 138 neutrons. It was once named Radiothorium, due to its occurrence in the disintegration chain of thorium-232. It has a half-life of 1.9116 years. It undergoes alpha decay to Ra. Occasionally it decays by the unusual route of cluster decay, emitting a nucleus of O and producing stable Pb. It is a daughter isotope of U in the thorium decay series. Th has an atomic weight of 228.0287411 grams/mole. Th is an isotope of thorium with 138 neutrons.

Th has an atomic weight of 228.0287411 grams/mole. 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… rcpw parts lookup
