Question

Beta Decay definition

simple

Answer 1

Beta decay is a type of radioactive decay in which a nucleus undergoes spontaneous transformation by emitting a beta particle. A beta particle can be an electron (e-) or a positron (e+). In beta minus decay (β- decay), a neutron within the nucleus is converted into a proton, and an electron and an antineutrino are emitted. In beta plus decay (β+ decay), a proton within the nucleus is converted into a neutron, and a positron and a neutrino are emitted. Beta decay occurs to achieve stability in an unstable or radioactive nucleus.
