How would you account for the following:   of the `d^(4)` species `Cr^(2+)` is strongly reducing while manganese(III) is strongly oxiding.   Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised.   The `D^(1)` configuration is very unstable in ions.
