Why the melting points of transition metals are very high and what is the trend of melting point across the period of 3d series?

Asked by Topperlearning User 26th June 2014, 10:07 AM
Answered by Expert

The high melting points of transition metals are due to the involvement of greater number of electrons of (n-1)d in addition to the ns electrons in the interatomic metallic bonding. Across a period of 3d series, the melting points of these metals increases to a maximum at d5 except for anomalous values of Mn and Tc decreases regularly as the atomic number increases.
