Ans. The melting point is a good measure of how much energy has to be inserted into the system to break the intermolecular bonds. Mn and Tc still forms these bonds, since these are present as a solid at some particular temperature.
However, the bonds they form are proportionally weaker because the electrons don't participate as strongly in the bonding. It's not that the density of electrons is lower in the delocalized system but that these electrons intrinsically have a lower stabilization resulting from the delocalization as compared to some other metal elements.
Thus, the bonds are weaker, the delocalized solid system is not as preferred, and less energy is necessary to melt the metal.
