Give reason Elements in the middle of the transition series have higher melting points.
The higher melting point of transition metals is due to the interatomic metallic bonding involving a bigger number of (n−1)d(n−1)d electrons in addition to the nsns electrons. Except for anomalous values of manganese and technetium, the melting points of these metals climb to a maximum at d5d5 as the atomic number increases during a period of 3d3d series.
