Ionization Energy: the amount of energy required to remove an electron from the atom or molecule in the gaseous state; the ionization energy increases as you go up the periodic table and to the right; the ionization
Ionization Energy - Ionization Energy of the Elements. It requires more energy to remove each successive electron. When all valence electrons have been removed, the ionization energy requires becomes more and more. It takes a lot of energy to remove core electrons.

Radioactive Decay: is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation. A material that spontaneously emits this kind of radiation—which includes the emission of energetic alpha particles, beta particles, and gamma rays—is considered RADIOACTIVE.
