The electron affinity is the energy associated with one mole of gaseous anions, from one mole of gaseous atoms, and one mole of electrons....
Explanation:
i.e. it is the enthalpy associated with the reaction....
Electron affinity generally increases across a Period (from left to right as we face the Table), and decreases down a Group.....
