Copper (I) compounds are white and diamagnetic while copper(II) compounds are coloured and paramagnetic. Explain.

The compounds of iron are coloured and paramagnetic. Explain.

Compounds of iron are coloured and paramagnetic. Explain.

Account for the following: (i) Copper (I) compounds are white whereas Copper (II) compounds are coloured. (ii) Transition metals and their compounds show catalytic activities. (iii) Zn,Cd,Hg are considered as d-block elements but not as transition elements (iv) Transition metals and many of their compounds show paramagnetic behaviour. (v) Transition metals can form alloy.

(a) Account for the following : (i) Copper(I) compounds are white whereas Copper(II) compounds are coloured. (ii) Chromates change their colour when kept in an acidic solution. (iii) Zn,Cd, Hg are considered as d-block elements but not as transition elements. (b) Calculate the spin only moment of Co^(2+) (Z=27) by writing the electronic configuration of Co and Co^(2+)
