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

Options

A. Nd
B. Yb
C. Ce
D. La

Answer

B

Explanation

`Yb(70) = 4f^14 6s^2`
`Yb^(+2) = 4 f^14 6s^0`
`:'` All the electrons are paired hence `Yb^(+2)` is diamagnetic.
