Lu

Vedclass · Answer

(D) The phenomenon of lanthanide contraction is observed in $4f$ elements due to the increase in effective nuclear charge as we move across the series. As a result,the atomic and ionic radii decrease continuously from lanthanum $(Z=57)$ to lutetium $(Z=71)$. Since lutetium $(Lu)$ is the last element in the lanthanide series,it has the highest effective nuclear charge and therefore the smallest ionic radius in the $+3$ state.

Identify the element having the smallest ionic size in the $+3$ state from the following.
