Which transition metal has the greatest number of oxidation state?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Mn.
To determine which transition metal has the greatest number of oxidation states, let's examine the common oxidation states for each of the given transition metals:
Oxidation States of Each Metal
1. Chromium (Cr):
Common oxidation states: +2, +3, +6
Total oxidation states: 3
2. Manganese (Mn):
Common oxidation states: +2, +3, +4, +6, +7
Total oxidation states: 5
3. Iron (Fe):
Common oxidation states: +2, +3
Total oxidation states: 2
4. Nickel (Ni):
Common oxidation states: +2, +3
Total oxidation states: 2
Conclusion
Based on the analysis, Manganese (Mn) has the greatest number of oxidation states, which are +2, +3, +4, +6, and +7.
Therefore, the correct answer is: Mn.
