Beta Particle Definition: An electron or positron. The term is generally applied to an electron or positron emitted in radioactive beta decay.
Beta particles are emitted by neutron rich unstable nuclei. Beta particles are high energy electrons. These electrons are not electrons from the electron shells around the nucleus, but are generated when a neutron in the nucleus splits to form a proton and an accompanying electron. Beta particles are negatively charged.
