After that time the nuclide decays through electron emission to protactinium-233, whose half-life is 26.967 days. The protactinium-233 nuclide in turn decays through electron emission to yield uranium-233. 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 232 Th is a fertile material able to absorb a neutron and undergo transmutation into the fissile nuclide uranium-233, which is the basis of the thorium fuel cycle.

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. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides. 232 Th decays via alpha decay into 228 Ra . Thorium-232 decays by kicking out a helium nucleus, two protons and two neutrons, becoming radium-228. One of those neutrons decays, sending out an electron and turning into a proton. 2008-05-05 As Uranium-238 loses an alpha particle it loses two protons and two neutrons.

The benefits are obvious: thorium is When thorium-232 absorbs a neutron, it becomes thorium-233, which has a half-life of only 22 minutes. Thorium-233 decays into protactinium-233 through beta decay . Protactinium-233 has a half-life of 27 days and beta decays into uranium-233; some proposed molten salt reactor designs attempt to physically isolate the protactinium from further neutron capture before beta decay can occur. Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.

The 4n chain of Th-232 is commonly called the Thorium Series. This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. How many protons in thorium-232. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide.

Name: Thorium: Symbol: Th: Atomic Number: 90: Atomic Mass: 232.038 atomic mass units: Number of Protons: 90: Number of Neutrons: 142: Number of Electrons: 90: Melting The two protons also have a charge of \(+2\). The top number, 4, is the mass number or the total of the protons and neutrons in the particle. Because it has two protons, and a total of four protons and neutrons, alpha particles must also have two neutrons. Alpha particles always have this same composition: two protons and two neutrons.
