Explanation:
The oxidation state of an element refers to the charge that the atom has in a compound or ion. It is represented by a Roman numeral that indicates the number of electrons gained or lost by the atom.
In this question, we need to determine which of the elements U, Th, Ac, and Pa exhibit only a +3 oxidation state.
Uranium (U)
- Uranium is a transition metal and can exhibit multiple oxidation states.
- The common oxidation states of uranium include +3, +4, +5, and +6.
- Therefore, uranium does not exhibit only a +3 oxidation state.
Thorium (Th)
- Thorium is also a transition metal and can have multiple oxidation states.
- The common oxidation states of thorium include +3 and +4.
- Therefore, thorium does not exhibit only a +3 oxidation state.
Actinium (Ac)
- Actinium is a rare earth metal and typically exhibits a +3 oxidation state.
- Therefore, actinium exhibits only a +3 oxidation state.
Protactinium (Pa)
- Protactinium is a transition metal and can have multiple oxidation states.
- The common oxidation states of protactinium include +3, +4, and +5.
- Therefore, protactinium does not exhibit only a +3 oxidation state.
Conclusion:
- Among the given elements, only actinium (Ac) exhibits only a +3 oxidation state.
