Q. Consider the following statements about transition metals.
I. These are very much hard and have low volatility.
II. Their melting and boiling points are high.
The correct statement(s) is/are (choose the appropriate option)

The d-and f-Block Elements

Solution:

The transition metals are very much hard and have low volatility. Their melting and boiling points are high. The high melting points of the $3 d, 4 d$ and $5 d$-transition metals are attributed to the involvement of greater number of electrons from $(n-1) d$ in addition to the $n s$ electrons in the interatomic metallic bonding.
