Why do the transition elements exhibit higher enthalpies of atomisation?

Text Solution

Verified by Experts

Because of large number of unpaired electrons in their atoms they have stronger interatomic interaction and hence stronger bonding between atoms resulting in higher enthalpies of atomisation.
