Nuclear Decay Definition. Nuclear decay or radioactive decay is the emission of energy and matter because of change in the nucleus of atom. The nuclear decay involves the emission of ionizing particles or ionizing radiation.
In particle physics, proton decay is a hypothetical form of radioactive decay in which the proton decays into lighter subatomic particles, such as a neutral pion and a positron.There is currently no experimental evidence that proton decay occurs.In the Standard Model, protons, a type of baryon, are theoretically stable because baryon number (quark number) is conserved (under normal circumstances; however, see chiral anomaly).or the type of radioactive decay in which a nucleus ejects a proton, see Proton emission.
