1.	Explain the following properties of transition elements. A) Colour. B) Oxidation State.
Answer» ..These elements show variable oxidation state because their VALENCE electrons in two DIFFERENT sets of ORBITALS, that is (n-1)d and ns. The energy DIFFERENCE between these orbitals is very less, so both the energy levels can be used for bond formation. Thus, TRANSITION elements have variable oxidation states.Maybe this can help you
