Concept Introduction:
Ionization energy is defined as the energy required to remove the valence electron of an atom when it is in gaseous state. In periodic table ionization energy of elements decreases down the column or group and increases across the row or period as it is inversely proportional to the atomic size.
Electron affinity is defined as the energy released when an electron is added (gained by an atom) to the atom in its gaseous state forming negative ion. In periodic table electron affinity of elements decreases down the column or group and increases across the row or period as it is inversely proportional to the atomic size.
