MHT CET · Chemistry · d and f Block Elements
Which element from following exhibits lowest number of different oxidation states?
- A Sc
- B Cu
- C Ti
- D Zn
Answer & Solution
Correct Answer
(D) Zn
Step-by-step Solution
Detailed explanation
As the number of unpaired electrons in 3d orbitals increases, the number of oxidation states shown by the element also increases. \(\mathrm{Zn}=[\mathrm{Ar}] 3 \mathrm{~d}^{10} 4 \mathrm{~s}^2\) shows only +2 oxidation state.
