Vedclass · Answer

(D) The lanthanoids are the elements from $Z = 57$ to $71$. $La$ $(Z = 57)$ is the first element of the $4f$ series and is often considered the prototype for lanthanoid chemistry due to its $3+$ oxidation state and ionic radius similarity. $Lu$ $(Z = 71)$ is the last element of the lanthanoid series. $Ce$ $(Z = 58)$ is a lanthanoid itself. $Lr$ $(Z = 103)$ is an actinoid. Among the given options,$La$ is the most characteristic element representing the lanthanoid series properties.
