Alpha decay: Alpha decay is a common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). A typical beta decay process involves carbon-14, often used in radioactive dating techniques. A heavy isotope is more likely to undergo beta decay, with one of the excessive neutrons transforming into an additional proton in the nucleus, moving the nucleus on step to the right in the Periodic Table, with no change in mass number. Ingamma decay, only energy, in the form of gamma rays, is emitted. These points present a simplified view of what beta decay actually is: 1) A neutron inside the nucleus of an atom breaks down, changing into a proton.
