Question

The melting point of transition metals is high because:

• A. of interatomic hydrogen bond formation.
• B. of interatomic metallic bond formation.
• C. of their ability to form ionic bonds
• D. All of the above.

Answer 1

The correct option is B of interatomic metallic bond formation.

Melting point of transition metal is high because of the involvement of greater number of electrons from $(n-1)d$ in addition to the $ns$ electrons in the interatomic metallic bonding.​
Generally, greater the number of unpaired electrons, higher is the melting point.
