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.
Name: Thorium Symbol: Th Atomic Number: 90 Atomic Mass: 232.0381 amu Melting Point: 1750.0 °C (2023.15 K, 3182.0 °F) Boiling Point: 4790.0 °C (5063.15 K, 8654.0 °F) Number of Protons/Electrons: 90 Number of Neutrons: 142 Classification: Rare Earth Crystal Structure: Cubic Density @ 293 K: 11.72 g/cm 3 Color: silvery Atomic Structure (1) Pb = 232 Th e λTh 232 t − 1 with Th and Pb as their atomic proportions and λ Th232 is the appropriate decay constant. This equation can be turned around to give: (2) t = ln Pb / 232 Th + 1 / λ Th 232 The atomic mass of thorium is 232 and its atomic number is 90. During the course of its radioactive disintegration `6 alpha` and `4 beta` particles are emitted. What is the atomic mass and atomic number of the atom?

When a nucleus of thorium-232 absorbs, or “captures,” a neutron, it becomes thorium-233, whose half-life is approximately 21.83 minutes. After that time the nuclide decays through electron emission to protactinium-233, whose half-life is 26.967 days. Thorium 232 is the most common isotope of thorium in the nature. 232Th is a fertile isotope, but is not capable of undergoing fission reaction after absorbing thermal neutron. The elements with an atomic number higher than 83 do not have stable isotopes: they are called radioelements. The naturally occurring radioelements are mainly found in thorium and uranium ores.

Nuclear Energy Agency/Organisation of Economic Co-operation and Development, Forty years of uranium resources, production and demand in perspective: The Red Book retrospective , NEA/OECD, Paris, 2006, p. 135. Thorium-232 is one of the small number of isotopes which can be made to undergo nuclear fission, so it could be employed as a nuclear fuel. Atomic data: Nuclear data: Index Periodic Table Chemistry concepts Reference Pauling Ch. 29 .
Atoms with the same atomic number but different neutron numbers are called isotopes isotopes within Earth are potassium-40, uranium-238, and thorium-232.
What is the atomic mass and atomic number of the 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,
