Concept Introduction:

Electron affinity:

The electron affinity ${\text{E}}_{\left(\text{a}\right)}$ of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.

  ${\text{X}}_{\left(\text{g}\right)}{\text{ + e}}^{\text{-}}\stackrel{}{\to }{\text{ X}}_{\left(\text{g}\right)}{}^{\text{-}}\text{ + energy}$
