Question:
What is the highest oxidation state exhibited by actinoids?
What is the highest oxidation state exhibited by actinoids?
Show Hint
Actinoids show greater variability in oxidation states compared to lanthanoids due to less effective shielding of 5f electrons.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understand oxidation states of actinoids.
Actinoids show a wide range of oxidation states due to the involvement of 5f, 6d, and 7s orbitals in bonding.
Step 2: Identify the maximum oxidation state.
Some actinoids such as neptunium and plutonium exhibit oxidation states as high as \(+7\).
Step 3: Conclusion.
Thus, the highest oxidation state exhibited by actinoids is \(+7\).
