Question:
Which of the following elements exhibits oxidation states other than +3?
Which of the following elements exhibits oxidation states other than +3?
Show Hint
Cerium is unique among lanthanides because it exhibits multiple oxidation states, including +4, in addition to the common +3.
Updated On: Jan 26, 2026
- Ce
- Gd
- Lu
- La
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the oxidation states.
Cerium (Ce) is a lanthanide element that exhibits oxidation states other than +3, including +4. The other elements listed (Gd, Lu, La) only exhibit the +3 oxidation state.
Step 2: Conclusion.
The correct answer is (A) Ce.
Cerium (Ce) is a lanthanide element that exhibits oxidation states other than +3, including +4. The other elements listed (Gd, Lu, La) only exhibit the +3 oxidation state.
