Web16 sep. 2024 · Ionization energy (IE) is the amount of energy required to remove an electron from an atom in the gas phase: A ( g) → A + ( g) + e − Δ H ≡ I E. IE is usually expressed in kJ/mol of atoms. It is always positive because the removal of an electron always requires that energy be put in (i.e., it is endothermic).
