Atom Review
... When atoms emit alpha, beta or gamma radiation, it is undergoing a radioactive decay. Decay occurs due to instability within the nucleus. As the ratio of protons to neutrons becomes more skewed, the nucleus becomes more unstable. All isotopes with an atomic number greater than 83 are unstabl ...
