Web26 de nov. de 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Oxygen in the gas phase, for example, gives off energy when it gains an electron to form an ion of Oxygen. O + e – → O – – ∆H = Affinity = 141 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity. Web22. It is the element with highest electronegativity value Answer: fluorine.
