The 4 n decay chain of 232 Th, commonly called the "thorium series" Thirty radioisotopes have been characterised, which range in mass number from 209 to 238. After 232 Th, the most stable of them (with respective half-lives) are 230 Th (75,380 years), 229 Th (7,340 years), 228 Th (1.92 years), 234 Th (24.10 days), and 227 Th (18.68 days).

The Element Thorium - Basic Physical and Historical Information. Atomic Number: 90 When bombarded with neutrons, thorium-232 becomes thorium- 233, which eventually decays into uranium-233 through a series of beta decays.

Also note that the mass of a particle that decays is greater than the sum of the What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle. An element X decays first by positron emission and then 2 α-particles are emitted in succession. If the product nucleus has mass number 229 and atomic number 8 The alpha decays cause the number of protons and neutrons to diminish by 2, lives for 4.47 billion years) and thorium 232 (with a half-life of 14.0 billion years).

It is an alpha emitter and goes through six alpha and four beta decay steps before becoming the stable isotope 208 Pb. 232 Th is sufficiently radioactive to expose a photographic plate in a few hours.

In fact, its half-life is considerably longer than the age of earth. The atomic mass of thorium is 232 and its atomic number is 90 . During the course of its radioactive disintegration 6alpha and 4beta - particles are emitted. The alpha decay of 232 Th initiates the 4n decay chain which includes isotopes with a mass number divisible by 4 (hence the name; it is also called the thorium series after its progenitor).

External gamma exposure is not a major concern because thorium emits only a small amount of gamma radiation. Although thorium-229 has a much higher gamma component than either thorium-232 or thorium-230, thorium-229 comprises a very small fraction of natural thorium. element that has an atomic number of 90 and a mass number of 232,0381 in the period 7 actanide series periodic table. Thorium-232 will undergo a process of decay from an unstable atomic nucleus to Thorium with atomic number 90 and symbol (Th), in its pure form, is a silvery white metal which is stable in air and remains lustrous for several months. Learn applications, properties and health effects of Thorium One example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208.
