FREE Expert Solution

Electron affinity is the energy change from the addition of 1 e to 1 mol of gaseous atoms or ions. This is the opposite of ionization energy.

Atom(g) + e → ion(g)         ΔE = –EA

This is a exothermic reaction as seen by the negative change in energy. Generally, electron affinity:
