Question

Manganese shows variable oxidation states (Mn, Z = 25) give reason​

Answer 1

a) Manganese shows maximum number of oxidation states. Theatomic number of manganese (Mn) is Z = 25. As all the 7 electrons of 3d and 4s can participate in bonding, hence Mn maximum number of variable oxidation states. ... As there are maximum number of unpaired electrons, hence Cr has highest melting point.
