Question:
Which of the following pair of actinoids exhibit maximum oxidation state of \(+7?\)
Which of the following pair of actinoids exhibit maximum oxidation state of \(+7?\)
Show Hint
The +7 state in actinoids is stabilized in highly oxidizing conditions, typically as dioxo cations like AnO\(_4^{3-}\).

The Correct Option is
Solution and Explanation
Step 1: Understanding the Concept:
Actinoids show variable oxidation states. The maximum +7 oxidation state is exhibited by Np, Pu, and Am.
Step 2: Detailed Explanation:
Neptunium (Np) and Plutonium (Pu) can exhibit +7 oxidation state (e.g., NpO\(_4^{3-}\), PuO\(_4^{3-}\)).
Th shows only +4, Pa shows +4 and +5, U shows +6 max, Cm shows +3/+4, Bk shows +3/+4, Fm shows +3.
Step 3: Final Answer:
The pair that exhibits maximum oxidation state of +7 is Np and Pu.
