How and you account for the following : (i) Cabalt (II) is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised. (ii) The transition elements exhibit high enthalpy of atomization. (iii) of the d^4 species, Cr^(2+) is strongly reducing while Mn (III) is strongly oxidsing .

(a) Describe the general trends in the following properties of the first series of the transition elements: (i) Stability of +2 oxidation state (ii) Formation of oxometal ions (b) Assign reason for each of the following: (i) Transition elements exhibit variable oxidation states. (ii)Transition metal ions are usually coloured

What are transition elements ? Explain that transition metal compounds are generally: (a) coloured (b) act as catalysts (c) show variable oxidation states. (d) form complexes (e) have high m.pt. and b.pt.
