The line sharpness may be attributed in part to the single, even-mass isotope, Th the observed isotope shift between Th 230 and Th 232 in wave number units. Le thorium (Th) comme tous les éléments de numéro atomique supérieur à celui du plomb, ne possède aucun isotope stable. Cependant, il possède six isotopes présents dans la nature et l'un d'eux, le thorium 232 (232Th), est relative The element numbers range from 90 to 96 - Thorium (no.

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. Atomic data: Nuclear data: Index Periodic Table Chemistry concepts Reference Pauling Ch. 29 . HyperPhysics: R Nave: Go Back: Thorium Nuclear Data.

Atomic mass of Thorium is 232.0381 u. Exact Mass: 232.03805 g/mol: Computed by PubChem 2.1 (PubChem release 2019.06.18) Monoisotopic Mass: 232.03805 g/mol: Computed by PubChem 2.1 (PubChem release 2019.06.18) Topological Polar Surface Area: 0 Å²: Computed by Cactvs 3.4.6.11 (PubChem release 2019.06.18) Heavy Atom Count: 1: Computed by PubChem: Formal Charge: 0: Computed by PubChem: Complexity: 0 232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th. The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days.

Jump to main content Within each series, therefore, the mass number of the members may be expressed as four times an appropriate integer (n) plus the constant for that series. As a result, the thorium series is known as the 4n series. The total energy released from thorium-232 to lead-208, including the energy lost to neutrinos, is 42.6 MeV. Th – Thorium Introduction Thorium is a member of the actinide series of elements, along with U and the human-made elements such as Pu. The element has an atomic number of 90, an atomic mass of 232, one main oxidation state (+4) and one naturally occurring isotope (232Th).
