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. Pauling first proposed the concept of electronegativity in 1932 to explain why the covalent bond between two different atoms (A–B) is stronger than the average of the A–A and the B–B bonds. According to valence bond theory, of which Pauling was a notable proponent, this "additional stabilization" of the heteronuclear bond is due to the contribution of ionic canonical forms to the bonding.
