- Scandium
- Titanium
- Nickel
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Analyzing Oxidation States of Each Element:
- Cobalt (Co): Cobalt commonly exhibits oxidation states of +2 and +3 in its compounds.
- Scandium (Sc): Scandium primarily shows an oxidation state of +3 and does not commonly exhibit any other stable oxidation states in its compounds.
- Titanium (Ti): Titanium can exhibit multiple oxidation states, commonly +2, +3, and +4.
- Nickel (Ni): Nickel commonly shows oxidation states of +2 and +3.
Conclusion:
Scandium is the only element among the options that shows only one stable oxidation state (+3) other than its elemental form. The correct answer is Option (2).
