Uranium-235 (U-235) Definition, Uses, Half-Life, & Facts

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.
