Question:
Which of the following does not show variable oxidation state?
Which of the following does not show variable oxidation state?
Show Hint
Look for elements with incomplete d-subshells for those exhibiting variable oxidation states.
Updated On: Jan 14, 2026
- Sc
- Mn
- Cr
- Cu
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Scandium (Sc) does not show variable oxidation states because its only stable oxidation state is +3. Elements like Mn, Cr, and Cu are known for exhibiting multiple oxidation states due to the availability of d-electrons.
