The Element Thorium - Basic Physical and Historical Information. Atomic Number: 90 When bombarded with neutrons, thorium-232 becomes thorium- 233, which eventually decays into uranium-233 through a series of beta decays.

2020-07-12 232 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. The resonance integral of thorium is one third that of 238 U and fewer neutrons are absorbed in 232 Th. Another factor is the loss of neutrons by absorption in the intermediate nuclide 233 Pa in the reaction chain of 232 Th to 233 U, which is much higher than in the corresponding intermediate nuclide 239 Np in the reaction chain of 238 U to 239 Pu. Atomic mass of Thorium is 232.0381 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Atomic Number of Thorium.

In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals. Twenty-seven radioactive isotopes of thorium, with mass number from 210 to 236, have been characterized. Naturally occurring thorium is composed mainly of one isotope: 232Th.

A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.
