WebSep 16, 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). WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Arsenic in the gas phase, for example, gives off energy when it gains an electron to form an ion of Arsenic. As + e – → As – – ∆H = Affinity = 78 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
