Thorium-232 is one of the small number of isotopes which can be made to undergo nuclear fission, so it could be employed as a nuclear fuel. The atom of thorium-232 contain 142 neutrons.For the other isotopes: number of neutrons = mass number - 90 2018-06-19 · chemical element with the atomic number of 90. Mass: 232.0377 ±0.0004 u Decay Chain of Thorium-232.svg 1,310 × 2,020; 13 KB. The packing fraction for the tin isotopes has been determined by Dr. Aston1 as 7· 3 ± 1. Using this value, the atomic mass of thorium (oxygen = 16·000) is 232· Symbol: Th. Atomic Number: 90. (protons in nucleus).

HyperPhysics: R Nave: Go Back: Thorium Nuclear Data. Z: A: Atomic Mass (u) Nuclear Mass(GeV/c2: Binding Energy element that has an atomic number of 90 and a mass number of 232,0381 in the period 7 actanide series periodic table. Thorium-232 will undergo a process of decay from an unstable atomic nucleus to One example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208. What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle.
