ionization potential

(ionization energy)
(energy needed to ionize an atom)

An atom's ionization potential or ionization energy is the energy (binding energy) required to remove an electron, thus ionizing it. The term work function has a similar meaning, but is specific to removing an electron from the surface of something metal ("everyday" metal, such as iron), taking into account the effects of the crystal structure, the surrounding atoms, etc.
