Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature. This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth.

Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature. This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. It has a decay energy of 0.39 MeV. It has a mass of 231.0363043 grams/mole. Thorium-232.

However, owing to significant abundance of its minor isotope 232 Th in deep-seawater, in 2013, the Commission recognized thorium as an element with two naturally-occurring isotopes and recommended A r (Th) = 232.0377(4).

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.

It has a decay energy of 0.39 MeV. It has a mass of 231.0363043 grams/mole. Thorium-232. 232 Th is the only primordial nuclide of thorium and makes up effectively all of natural thorium, with other isotopes of thorium appearing only in trace amounts as relatively short-lived decay products of uranium and thorium.

Th is atomic number 90, so: Final mass number = 232 - 6*4 - 4*0 = 208. Final atomic number = 90 - 6*2 - 4*(-1) = 82 The end product of this radioactive element is an isotopes of lead (atomic mass 208 and atomic number 82 ).
