Why do transition metals exhibit higher enthalpies of atomisation ?

Text Solution

Verified by Experts

Enthalpy of atomisation is the amount of heat required to break the metal lattice of get free atoms. As transition metals contain a large number of unpaired electrons, they have strong interatomic attractions ( metallic bonds). Hence, they have high enthalpies of atomisation.
