Why is the enthalpy of atomisation also the bond enthalpy?

My book says that the enthalpy of atomisation is the enthalpy change when one mole of its atoms in the gaseous state is formed from the element under standard conditions.
eg. C(graphite)➙ C(g)
That is all alright.
But then it talks about bond enthalpy and then says,
 CH4(g) ➙ C(g) + 4H(g) is the reaction for atomisation of CH4(g)
How does this fit the definition of enthalpy of atomisation?? Coz it is defined when one mole of its gaseous atoms is formed from its elements. 
 The reaction doesn't look like atomisation at all.

Yeah I think I get it. Thanks a lot


Apurva S.

does it mean enthalpy of formation is equal to enthalpy of atomization
