$La^{3+}$

Vedclass · Answer

(D) The ionic size of trivalent ions generally increases down a group due to the addition of new shells. $Ti^{3+}$ belongs to the $3d$ series,$Zr^{3+}$ to the $4d$ series,and $Hf^{3+}$ to the $5d$ series. $La^{3+}$ is a lanthanide ion with a larger atomic radius compared to the transition metal ions listed. Among the given options,$La^{3+}$ has the largest ionic radius due to its position in the $6th$ period and the lanthanide contraction effect being less pronounced for $La^{3+}$ compared to the subsequent $Hf^{3+}$ ion.
