Why is manganese not a transition metal?

Transition metal should exhibit following characteristics: 1. It should have partially filled d orbitals . It should not have completely filled d orbitals. 2. The valence configuration should have at least an unpaired electron. 3. read more

Transition metal should exhibit following characteristics: 1. It should have partially filled d orbitals . It should not have completely filled d orbitals. 2. The valence configuration should have at least an unpaired electron. 3. It shows variable oxidation States. Manganese satisfies all three condition. So I think manganese is a transition metal. read more
