Ionization energy

Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic process. Roughly speaking, the closer the outermost electrons are to the nucleus of the atom, the higher the atom''s ionization energy. In physics, ionization energy is usually expressed in electronvolts (eV) or joules (J).
