How to measure electron affinity
WebElectron affinity is a measure of the energy released when an extra electron is added to an atom. Electron affinities are measured in the gaseous state. In general, electron affinities become more negative as we move from left to right on the periodic table. In general, electron affinities become less negative from top to bottom of a group.
