    K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7

    @pooja195 is correct. Mn is one of the only first row transition metals known to carry +7 charge.
