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