The thorium series is one of three classical radioactive series beginning with naturally occurring thorium-232.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved.


Solution for The radioactive decay of thorium-232 occurs in multiple steps, called a radioactive decay chain. The second product produced in this chain is…

If the radioactive decay of Thorium- (232 The radioactive decay series of 232 Th is complex and produces alpha, beta, and gamma radiation. The figure below shows the important isotopes in the decay series, indicates whether the primary decay mode is via alpha or beta emission, and gives the half-life. 232 Th is the predominant isotope of natural thorium.

The details in decay chain (symbol, atomic mass, number of protons, half-life, decay children) are taken from Wolfram Alpha. Image source: Modified by Chloe Reynolds based on the Thorium SVG image by Wikipedia contributor BatesIsBack .

What is the product of these two decay steps? 232Th → α  O. A. Pringle. The radionuclide U-232 alpha-decays into Th-228.

These 4 He atoms can be trapped in the crystal lattice and accumulate over geologic time. the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials.

Thorium 232 alpha decay

In the thorium decay series, thorium- 232 loses a total of 6 \alpha particles and 4 \beta particles in a 10 -stage process. What is the final isotope produced?

Thorium-232 undergoes an alpha decay, followed by a B-decay. What is the product nucleus of this two-step decay? Thorium is element 90. (a) 239 Pa (b) 238 Pa (c) 239 Ac (a) 238 AC Ra 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. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.

The 4n chain of Th-232 is commonly called the "thorium series" or "thorium cascade". Beginning with naturally occurring thorium-232, this series includes the following elements: actinium, bismuth, lead, polonium, radium, radon and thallium. All are present, at least transiently, in any natural thorium-containing sample, whether metal, compound
