CBSE Class 12-science Answered
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 | 26 Jun, 2014, 10:07: AM
Expert Answer
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.
