Why do the elements of chromium group have high melting points ?

Text Solution

Verified by Experts

The elements of the chromium group have the highest number of unpaired electrons in their valence shell. (For instance, the electronic configuration of `Cr : [Ar]3d^(5)4s^(1)`). These unpaired electrons are involved in the formation of strong metallic bonds. Hence, the elements of chromium group have very high melting points.
