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