Which of the following lanthanoid ions is diamagnetic?
- A.Ce3+
- B.Eu2+
- C.Yb2+Correct answer
- D.Sm3+
Solution
Yb (atomic number 70) has the electronic configuration . Therefore, Yb2+ has the configuration , meaning all -orbitals are completely filled with paired electrons, making it diamagnetic.
