A beta particle is either an electron or a positron emitted by an atomic nucleus in beta decay, which is a type of radioactive decay. The phenomenon of beta decay involves a c â¦ hange within the atomic nucleus of an atom.nswer by Quirkyquantummechanic. Confidence votes 77.5K. A beta particle is two particles emitted in the form of radioactive decay called beta decay. It is either an electron and an electron anti neutrino, which is emitted in beta-decay, or a positron and an electron neutrino, which is emitted in beta+ decay.
