Vedclass · Answer

(B) The general electronic configuration of lanthanoids (elements with atomic numbers $57$ to $71$) is represented as $[Xe] \, 4f^{1-14} \, 5d^{0-1} \, 6s^2$. In this configuration,the $4f$ orbitals are progressively filled from $1$ to $14$,while the $5d$ orbital may contain $0$ or $1$ electron,and the $6s$ orbital is completely filled with $2$ electrons.
