The four most common modes of radioactive decay are: alpha decay, beta decay, inverse beta decay (considered as both positron emission and electron capture), and isomeric transition. Of these decay processes, only alpha decay (fission of a helium-4 nucleus) changes the atomic mass number ( A ) of the nucleus, and always decreases it by four.
alpha decay. Also α-decay. A type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms or "decays" into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. alpha particle (α) Also symbolized by α 2+, He 2+, and 4 2 He 2+.
Except for beryllium-8 and beta-delayed alpha emission branches in some lighter nuclides, tellurium (104 Te to 109 Te) is the second lightest element with isotopes known to undergo alpha decay, antimony being the lightest.

Alpha decays are registered by the emitted alpha particles, and the decay products are easy to determine before the actual decay; if such a decay or a series of consecutive decays produces a known nucleus, the original product of a reaction can be easily determined.
