The Beta Particle. Beta decay is a radioactive process in which an electron is emitted from the nucleus of a radioactive atom, along with an unusual particle called an antineutrino.The neutrino is an almost massless particle that carries away some of the energy from the decay process.ecause this electron is from the nucleus of the atom, it is called a beta particle to distinguish it from the electrons which orbit the atom. Like alpha decay, beta decay occurs in isotopes which are neutron rich (i.e. have a lot more neutrons in their nucleus than they do protons).
After a radioactive nucleus has emitted a beta particle, the mass number stays the same and the atomic number goes up by 1. A neutron in the nucleus has changed into a proton plus an electron. The proton stays inside the nucleus but the electron is emitted as a beta particle.fter a radioactive nucleus has emitted a beta particle, the mass number stays the same and the atomic number goes up by 1. A neutron in the nucleus has changed into a proton plus an electron. The proton stays inside the nucleus but the electron is emitted as a beta particle.
