So electron affinity is the enthalpy change associated with the rxn: M (g) + e− → M −(g) How should this evolve across a Period from left to right?As the name suggests, electron affinity is the ability of an atom to accept an electron. Unlike electronegativity, electron affinity is a quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The more negative the electron affinity value, the higher an atom's affinity for electrons.Electron affinity is the amount of energy released when an electron is added to a neutral atom in the gaseous state. In other words, when an electron is added to a neutral atom, energy will be released, but the amount will depend on several things. The atomic radius and effective nuclear charge being two main things. What does electron affinity measure.
