232Th is a fertile isotope, but is not capable of undergoing fission reaction after absorbing thermal neutron. Thorium is a naturally-occurring chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. The chemical symbol for thorium is Th. Thorium was discovered in 1828 by norwegian mineralogist Morten Thrane Esmark. Four-fifths of the thorium present at Earth's formation has survived to the present. 232 Th is the only isotope of thorium occurring in quantity in nature. Its stability is attributed to its closed nuclear subshell with 142 neutrons.

Diagram of the nuclear composition, electron configuration, chemical data, and valence (outer electron) orbitals of an atom of thorium-232 (atomic number: 90), the most stable isotope of this element. The nucleus consists of 90 protons (red) and 142 neutrons (orange). 90 electrons (white) successively occupy available electron shells (rings).

The fourth chain has no such long lasting bottleneck isotope, so almost all of the isotopes in that chain have long since decayed down … Thorium oxide is used as a catalyst in the production of sulfuric acid (H 2 SO 4), in the cracking of petroleum products and in the conversion of ammonia (NH 3) to nitric acid (HNO 3). Thorium's most stable isotope , thorium-232, has a half-life of about 14,050,000,000 years. Technical data for Thorium Click any property name to see plots of that property for all the elements. Both in atomic mass, and in density, Uranium is “heaviest” of these two.
