Which one of the following lanthanides exhibits +2 oxidation state with diamagnetic nature? (Given Z for Nd = 60, Yb = 70, La = 57, Ce =58) 14 2 2+ 14 (A) Nd (B) Yb (C) La (D) Ce

Question

Which one of the following lanthanides exhibits +2 oxidation state with diamagnetic nature? (Given Z for Nd = 60, Yb = 70, La = 57, Ce =58) 14 2 2+ 14

(A) Nd
(B) Yb
(C) La
(D) Ce

Prashant Kotian · Accepted Answer

Correct answer: B) YB. Electronic configuration of Yb = [Xe] 4f 6s Thus, electronic configuration of Yb = [Xe] 4f Since all the electrons are paired, the ion is diamagnetic.
