Vedclass · Answer

$(A)$ The atomic radius of $Zn$ is $137 \ pm$.The atomic radius of $Fe$ is $126 \ pm$.The ionic radius of $Fe^{2+}$ is $77 \ pm$.The ionic radius of $Fe^{3+}$ is $63 \ pm$.Comparing these values: $137 \ pm > 126 \ pm > 77 \ pm > 63 \ pm$.Therefore, the correct order of size is $Zn > Fe > Fe^{2+} > Fe^{3+}$.Hence, the correct option is $A$.
