Which one of the following lanthanide ions does not exhibit paramagnetism?

Question

Accepted Answer

Correct answer: A. (a) Generally, paramagnetism is shown by lanthanoid ions. The paramagnetism arises due to presence of unpaired electrons in f-orbital. Lu^3+ : [ Xe ]4f^14 (Diamagnetic) Ce^3+ : [ Xe ]4f^1 (Paramagnetic) Eu^3+ : [ Xe ]4f^6 (Paramagnetic) Yb^3+ : [ Xe ]4f^13 (Paramagnetic) Lu^3+ (4f^14 ) does not have unpaired electrons. Hence, it does not exhibit paramagnetism.
