Mn exhibits high oxidation states in the oxides, for example:inMn2O7the oxidation state of Mn is +7. They show variable oxidation states as both (n–1)d and ns electrons participate in bonding, due to nearly same energy levels. In transition elements, the oxidation state can vary from +1 to the highest oxidation state by removing all its valence electrons. For example, iron can exist in 0, +2 or +3 oxidation state. In p-block elements we have seen lower oxidation states are favoured by the heavier members (due to inert pair effect) whereas, we acknowledge an opposite trend in d-block. Sol: In the first series of transition elements, the oxidation states which lead to exactly half-filled or completely filled d-orbitals are more stable. The elements in the first-half of the transition series exhibit many oxidation states with Mn exhibiting maximum number of oxidation states (+2 to +7). Distinctions between methods for stabilizing OSs in compounds in solution and in a solid state are discussed. Stability of oxidation states Higher oxidation states are shown by chromium, manganese and cobalt. Transition elements (also known as transition metals) are elements that have partially filled d orbitals. Oxidation State. The relative stability of the +2 oxidation state increases on moving from top to bottom. The stability of any oxidation state of any element generally depends upon the electronic configuration of that particular ion.
