Question

Transition metals with highest melting point is ____________.

विकल्प

• Hg

• Cr

• Sc

• W

Answer 1

Transition metals with highest melting point is W.

Explanation:

The high melting points of these metals are attributed to the involvement of a greater number of electrons from (n − 1)d in addition to the ns electrons in the interatomic metallic bonding. W belongs to the 5d series and it has a lot of unpaired electrons (5d⁴ 6s²).
