Name a transition element which does not exhibit variable oxidation states
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Sc
The transition element that does not exhibit variable oxidation states is: Scandium (Sc)
Sc shows almost exclusively the +3 oxidation state.
Others show variable oxidation states:
- Mn (Manganese): Shows +2, +3, +4, +5, +6, +7 (maximum range)
- Fe (Iron): +2 and +3 (common), also +6 in some compounds
- Cu (Copper): +1 and +2
