Elements which generally exhibit variable oxidation states and form colored ions are ___________.
Elements which generally exhibit variable oxidation states and form colored ions are ___________.
Open in App
Solution
The correct option is B transition elements
Transition elements have vacant d orbitals and the energy gap between d orbitals is very less. So transition elements exhibit variable oxidation state and form coloured ions as these elements emit radiations due to excitation of d electrons.
