 Definition: Enthalpy of atomization is the amount of enthalpy change when a compound'sbonds are broken and the component atoms are reduced to individual atoms.

Enthalpy of atomization is denoted by the symbol ΔHa.            

                                                                                                                       OR

 Enthalpy change on breaking one mole of bonds completely to obtain atoms in the gas phase is called enthalpy of atomization.
