Given example and suggest reasons for the following features of the transition metal :
A transition metal exhibits highest oxidation state in oxides and fluorides.

Text Solution

Verified by Experts

Oxygen and fluorine are strong oxidising agents due to their small size and high electronegativity. Hence, they can oxidise metals to the highest oxidation states, e.g., vanadium shows an oxidation state of +5 in `V_(2)O_(5)` and chromium shows an oxidation state of + 6 in `CrF_(6)`.
