In nuclear physics, beta decay (Î²-decay) is a type of radioactive decay in which a beta ray, and a respective neutrino are emitted from an atomic nucleus.
When a neutron breaks down into a proton and electron it is called decay. In this specific case it is Beta - (minus) decay since it is producing an electron (it also produces an electron antineutrino).
