Question

What is the highest oxidation state possible for a transition element?

• A. +1
• B. +3
• C. +5
• D. +7

Hint:

Transition elements can achieve high oxidation states due to the involvement of both the s and d orbitals in bonding.

Answer 1

The Correct Option is D

Step 1: Understanding oxidation states.
The highest oxidation state for a transition metal is typically determined by the number of electrons in its outermost shell. For elements in the transition series, the highest oxidation states are often achieved by using both the s and d orbitals.
Step 2: Analyzing the options.
(A) +1: Incorrect. This is a low oxidation state and is rarely the highest for transition elements.
(B) +3: Incorrect. Although +3 is common, it is not the highest oxidation state possible.
(C) +5: Incorrect. Some transition elements can reach +5, but this is not the highest.
(D) +7: Correct. The highest oxidation state in transition elements is +7, as seen in elements like manganese (Mn).
Step 3: Conclusion.
The correct answer is (D) +7, which is the highest oxidation state that can be achieved by transition elements.
