What is the atomic mass and atomic number of the final atom? Thorium – Atomic Number – Atomic Mass – Density of Thorium Atomic Number of Thorium. Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 Atomic Mass of Thorium. Atomic mass of Thorium is 232.0381 u. Note that, each element may contain more isotopes, Thorium (Th). Diagram of the nuclear composition, electron configuration, chemical data, and valence (outer electron) orbitals of an atom of thorium-232 (atomic number: 90), … It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Th-232 (Thorium, atomic number Z = 90, mass number A = 232).

Spin. Thorium has six naturally occurring isotope s, none of these isotopes are stable. However, one isotope, 232 Th, is relatively stable, with a half-life of 14.05 billion years.

Thorium-232 can be converted into thorium-233 by bombardment with the first of the transuranium elements, which have higher atomic numbers than uranium.

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.

All are unstable with the most stable being 232 Th with a half-life of 14.05 billion years. Thorium-232 represents all but a trace of naturally occurring thorium.
