What is the reason behind the high melting points of transition metals?

Options

  1. AGreater involvement of ns electrons
  2. BGreater involvement of (n-1)d electrons
  3. CStrong interatomic repulsion
  4. DLow number of valence electrons

Correct answer

B. Greater involvement of (n-1)d electrons

Step-by-step solution

The the high melting points of transition 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.
