Ans. Enthalpy of atomisation is the change in enthalpy when one mole of bonds are completely broken to obtain atoms in the gas phase.

Transition elements or D-Block elements have high effective nuclear charge and a large number of valence electrons. Therefore, they form very strong metallic bonds. As a result, the enthalpy of atomization of transition metals is high.
