Vedclass · Answer

(D) Lanthanum $(Z = 57)$ has the electronic configuration $[Xe] 5d^1 6s^2$. Although it does not have any electrons in the $4f$ orbital in its ground state,it is considered the first member of the lanthanoid series because its chemical properties are very similar to the elements of the $4f$ block (lanthanoids). Therefore,it is grouped with the $f-$block elements.

Lanthanum $(La)$ is grouped with $f-$block elements because
