Which from following lanthanoids exhibits +4 oxidation state in \(\mathrm{F}^7\) configuration?
- A Ce
- B Yb
- C Eu
- D Tb
Answer & Solution
Correct Answer
(D) Tb
Step-by-step Solution
Detailed explanation
Terbium (Tb) has electronic configuration \( [\mathrm{Xe}] 4f^9 6s^2 \). In the +4 oxidation state, Tb loses four electrons \( (2 \text{ from } 6s \text{ and } 2 \text{ from } 4f) \).
