What is the reason the enthalpies of atomisation of the transition metals are high?

Options

  1. ATransition metals have fewer electrons compared to non-transition metals.
  2. BTransition metals have completely filled d-orbitals.
  3. CTransition metals have a high atomic number.
  4. DBecause of large number of unpaired electrons in their atoms, transition elements have stronger interatomic in

Correct answer

D. Because of large number of unpaired electrons in their atoms, transition elements have stronger interatomic in

Step-by-step solution

Correct Option is : (D) Because of large number of unpaired electrons in their atoms, transition elements have stronger interatomic interaction and hence stronger bonding between atoms resulting in higher enthalpies of atomization.
