Vedclass · Answer

(A) The electronic configuration of Gadolinium ($Gd$,$Z=64$) is $[Xe] 4f^7 5d^1 6s^2$. In this configuration,one electron enters the $5d$ orbital due to the stability provided by the half-filled $4f^7$ subshell. For other lanthanoids like $Eu$ $(Z=63)$,$Tb$ $(Z=65)$,and $Dy$ $(Z=66)$,the $5d$ orbital remains empty in their ground state configurations as electrons fill the $4f$ subshell.

In the electronic configuration of which of the following elements is an electron arranged in the $5d$ orbital?
