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.
As in all nuclear decays, the decaying element (in this case 14 6C) is known as the parent nuclide while the resulting element (in this case 14 7N) is known as the daughter nuclide. The emitted electron or positron is known as a beta particle.
