The d-And-f-Block Elements
Question
Wired Faculty App

What is the reason for the high melting points of d-block elements?

Answer

The melting points depend upon the inter atomic bonding, more the number of electrons given by a metal higher in its interatomic bonding (metallic bonding) and thus higher will be its melting point.
In d-block elements due to the involvement of both ns and (n – 1)d electrons, the number of electrons involved are higher and therefore stronger interatomic bonding and higher melting point.
