Enthalpy of atomisation (∆atH) is enthalpy change involved when one mole of gaseous atoms is formed from a substance in elemental state.
For eg. Na(s) ------> Na(g)
On the other hand bond enthalpy/bond energy/bond dissociation enthalpy is the energy required to break one mole of bond to give separated atoms in gaseous state.
For eg. HBr ------> H(g) + Br(g)
