Is bond dissociation the same as atomisation?
Bond dissociation is twice the enthalpy of atomisation for diatomic elements.

So is the link wrong. The link says in hydrogen bond dissociation is equal to enthalpy of atomisation for diatomic elements too
Im confused.

Many sources say both but can they be both at the same time?
These statements seem contradictory.

One forms a mol of gaseous atoms.
One breaks a mol of bonds in gaseous molecules.

If you break a mol of bonds in diatomic molecules, you'll form 2 mol of gaseous atoms.

But how can it be both?
Eg twice bond enthalpy and equal to bond enthalpy?

It can't and it isn't.
