Practice question from The d- and f-Block Elements (NEET Preparation Chemistry), with the correct answer and a step-by-step solution.
medium · MCQ · Q-70EC37
Why do transition elements exhibit higher enthalpies of atomization?
- A.Due to absence of vacant d-orbitals
- B.Due to involvement of a large number of electrons from in addition to electrons in interatomic bondingCorrect answer
- C.Due to completely filled -orbitals leading to stable configurations
- D.Due to very small atomic radii of transition elements
Solution
Transition elements have strong interatomic bonding due to the participation of both and electrons in metallic bonding, which results in a greater number of unpaired electrons available for bonding, hence higher enthalpies of atomization.
