WebIntroduction. Thorium is a chemical element with the atomic number 90 in the periodic table. The average concentration of this substance in the upper crust of Earth amounts to 10.5 ppm, while thorium concentration in the middle layer (the mantle) is around 6.5 ppm. The core (lowest layer) of the Earth’s crust contains 1.2 ppm on average. WebThorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in 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. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays …
