Radioactive decay is the process by which a radioactive atom emits particles and energy to reach a more stable configuration. Atoms may emit alpha or beta particles from the nucleus or may spontaneously split into differ...

Atoms become radioactive when they have an excess of protons or neutrons in the nucleus, leading to unbalanced internal forces, which the atom balances by emitting radiation. Atoms with a different amount of neutrons or ...
