Question

Which of the following element having high melting and boiling point. *​

Answer 1

Explanation:

The high melting and boiling points of d-block metals are attributed to the involvement of greater number of electrons from (n-1)d in addition to the ns electrons in the interatomic metallic bonding. In any row, the melting points of these metals rise to a maximum at d⁵ except for anomalous values of Mn and Tc and fall regularly as the atomic number increases.

hope it helps you
