Vedclass · Answer

(C) The atomic number of Gadolinium $(Gd)$ is $64$. Following the Aufbau principle and the stability of half-filled orbitals,the $4f$ subshell is half-filled at Europium ($Eu$,$Z = 63$) with the configuration $[Xe] 4f^7 6s^2$. For the next element,Gadolinium $(Z = 64)$,the $4f$ subshell is already stable (half-filled),so the next electron enters the $5d$ orbital instead of the $4f$ orbital. Therefore,the electronic configuration of $Gd$ is $[Xe] 4f^7 5d^1 6s^2$.

The electronic configuration of Gadolinium ($Gd$,$Z = 64$) is:
