Q. Most of the transition metals exhibit
(i) paramagnetic behaviour
(ii) diamagnetic behaviour
(iii) variable oxidation states
(iv) formation of coloured ions

Solution:

Due to presence of unpaired electrons in orbitals, the most of the transition metal ions and their compounds are paramagnetic. They form coloured ions and show variable oxidation states also due to presence of vacant d-orbitals.
