Transition elements exhibit variable oxidation states.

Vedclass · Answer

(C) Transition elements are characterized by the presence of partially filled $d$-orbitals. Due to the presence of unpaired electrons,they exhibit variable oxidation states. They have high enthalpies of atomization due to strong interatomic interactions. They act as good catalysts because of their ability to adopt multiple oxidation states and provide a large surface area for reactions. Therefore,the statement that transition elements exhibit variable oxidation states is correct.
