What is Electron Affinity?
Electron affinity is the energy change that occurs when an electron is added to a neutral atom in the gaseous state to form a negative ion. A more negative electron affinity indicates a greater tendency to gain electrons. Halogens have the highest (most negative) electron affinities, as they require only one electron to achieve a noble-gas configuration.
