Suggest reasons for the following features of transition metal chemi

1.	Suggest reasons for the following features of transition metal chemistry :(i) The transition metals and their compounds are usually paramagnetic.(ii) The transition metals exhibit variable oxidation states.
Answer» (i) Due to presence of unpaired electrons in d-orbitals. (ii) Due to incomplete filling of d- orbitals.Due to very small energy difference in between (n-1)d and n s - orbitals.
