WHY IS THEIR A DiP IN METLING POINT FOR Cr to Mn

The electronic configuration of Sc, Ti, V, Cr is given below:

Sc: 3d1 4s2  Number of unpaired electrons : 1

Ti: 3d2 4s2  Number of unpaired electrons : 2

V: 3d3 4s2  Number of unpaired electrons : 3

Cr: 3d5 4s1  Number of unpaired electrons : 6

As the number of unpaired electron increases, the strength of metallic bond, between two metal atoms increases, which leads to increase in melting point of the metals.

Manganese's electronic configuration is 3d54s2 and, the number of unpaired electron is 5 (lesser than Cr which has 6 unpaired electron), therefore the strength of interatomic interaction in Mn, is less than that of Cr. Hence, there is a dip in the melting point of Mn
