Nuclear Chemistry

Nuclear Chemistry. Radioactivity. Radioisotopes are unstable isotopes whose nuclei gain stability by spontaneously undergoing changes. These changes are accompanied by the emission of large amounts of energy. Radioactive decay is the process by which materials give off this energy.
