Vedclass · Answer

(D) Transition metals have high enthalpies of atomisation because of the strong interatomic interactions.These strong interactions are primarily due to the presence of a large number of unpaired electrons in their $(n-1)d$ orbitals.These unpaired electrons participate in metallic bonding,which leads to stronger metallic bonds compared to other elements.Therefore,more energy is required to break these bonds to atomise the metal.
