Why do the transition elements exhibit higher enthalpies of atomisation?

Options

  1. ABecause Transition elements have more protons in their nuclei.
  2. BBecause Transition elements have a larger number of valence electrons.
  3. CBecause of the large number of unpaired electrons in their atoms they have stronger interatomic interaction an
  4. DBecause Transition elements have a smaller atomic radius compared to other elements.

Correct answer

C. Because of the large number of unpaired electrons in their atoms they have stronger interatomic interaction an

Step-by-step solution

Correct Option is : (C) Because of the 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.
