Vedclass · Answer

(D) The electronic configuration of $Ce$ $(Z = 58)$ is $[Xe] 4f^1 5d^1 6s^2$. By losing four electrons,it achieves the stable noble gas configuration of $Xe$,thus exhibiting a $+4$ oxidation state. $La$ $(Z = 57)$ typically shows a $+3$ state. $Eu$ $(Z = 63)$ and $Gd$ $(Z = 64)$ typically show $+3$ states,with $Eu$ also showing $+2$.
