Vedclass · Answer

(B) Transition metal elements exhibit variable oxidation states due to the participation of $(n-1)d$ and $ns$ electrons in bonding.They show catalytic properties due to their ability to adopt multiple oxidation states and provide a large surface area.They exhibit both paramagnetic and diamagnetic properties depending on the presence of unpaired electrons.However,not all their ions are colored. Ions with $d^0$ or $d^{10}$ electronic configurations (e.g.,$Sc^{3+}$,$Zn^{2+}$,$Cu^+$) are colorless because they lack unpaired electrons for $d-d$ transitions.Therefore,the statement that all their ions are colored is incorrect.
