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

  1. A Nd
  2. B Yb Correct answer
  3. C La
  4. D Ce

Solution

Yb (70) = 4f<sup>14</sup> 6s<sup>2</sup> <br><br>Yb<sup>+2</sup> = 4f<sup>14</sup> 6s<sup>0</sup> <br><br>$\because$ All the electrons are paired hence Yb<sup>+2</sup> is diamagnetic.
