What are alpha, beta, and gamma decay?

Answer 1

Alpha decay is a form of radioactive decay in which an atomic nucleus ejects an alpha particle through electromagnetic force and transforms into a nucleus with mass number 4 less and atomic number 2 less.

Beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−), while in the case of a positron emission as "beta plus" (β+).
In β− decay, the weak interaction converts a neutron (n0) into a proton (p+) while emitting an electron (e−) and an anti-neutrino (νe)

Gammay decay is a type of radioactivity in which some unstable atomic nuclei dissipate excess energy by a spontaneous electromagnetic process. In the most common form of gamma decay, known as gamma emission, gamma rays (photons, or packets of electromagnetic energy, of extremely short wavelength) are radiated.

Answer 2

Alpha decay contains hydrogen (or helium, its been a together as by using fact that chem) debris. Beta decay is electron. Gamma is potential. (so as from least-superb) Alpha may well be blocked by potential of paper. Beta, by potential of something like plywood, and gamma by potential of lead block. i do no longer think of denims are sufficient, neither is iciness coat till its somewhat thick and dense.

Answer 3

Just to add to the previous answer, an alpha particle can also be called a helium nucleus.
