8.31 (i) Of the d4 species, Cr²⁺ is strongly reducing while manganese (III) is strongly oxidizing: The +2 oxidation state becomes more stable on moving across a period i.e. the tendency of metals to give electrons becomes more. Therefore, vanadium(II) oxide and chromium(II) oxide are strong reducing
