Web26 nov. 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Gallium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Gallium. Ga + e – → Ga – – ∆H = Affinity = 28.9 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
