Beta Particle Definition: An electron or positron. The term is generally applied to an electron or positron emitted in radioactive beta decay.
Beta decay. In Beta decay a neutron changes into a proton plus an electron. The proton stays in the nucleus and the electron leaves the atom with high energy, and we call it a beta particle. When a beta particle is emitted from the nucleus the nucleus has one more proton and one less neutron.
