Enthalpy of atomisation, ΔaH0, is the change in enthalpy when one mole of bonds are completely broken to obtain atoms in the gas phase. For example: atomization of methane molecule.

CH4 (g) → C (g) + 4H (g)        ΔaH0= 1665.0 kJ mol-1

 

For diatomic molecules enthalpy of atomization is equal to the enthalpy of bond dissociation. For example: atomization of dihydrogen molecule.

H(g) → 2H (g);                  ΔaH0= 435.0 kJ mol-1
