Answer:
Manganese has 5 free electrons in its d orbital so it take place more in metallic bonding as compared to other elements in its neighborhood (left and right in periodic table) who have 4 free electrons in their d orbital. More metallic bonding means more energy requires in breaking bond and more melting point.

Answer:
it is so because mn and tc are half filled and as being half filled element they rarely interact with each other and hence they inter metallic bonding is low which turns in low melting points.
