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.
A high-speed electron emitted by an atomic nucleus undergoing radioactive decay. A beta particle is created when a neutron becomes a proton. Beta particles have greater speed and penetrating power than alpha particles. â¦ The process by which a neutron becomes a proton and emits an electron is called beta decay. Beta decay results in the atomic number of an element being increased by one and its mass number staying the same. See more at radiation, radioactive decay.
