Principles of Nuclear Power

232Th 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. The atomic mass of thorium is 232 and its atomic number is 90. During the course of its radioactive disintegration 6alpha and 4beta - particles are emitted. What is the atomic mass and atomic number of the final atom? 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.
