$$\begin{gathered} \mathrm{Ge}(\mathrm{Z}=32)\to \left[\mathrm{Ar}\right]3{\mathrm{d}}^{10}4{\mathrm{s}}^{2}4{\mathrm{p}}^2;\mathrm{Se}(\mathrm{Z}=34)\to \left[\mathrm{Ar}\right]3{\mathrm{d}}^{10}4{\mathrm{s}}^{2}4{\mathrm{p}}^4 \\ \mathrm{Te}(\mathrm{Z}=52)\to \left[\mathrm{Kr}\right]4{\mathrm{d}}^{10}5{\mathrm{s}}^{2}5{\mathrm{p}}^4;\mathrm{Sb}(\mathrm{Z}=51)\to \left[\mathrm{Kr}\right]4{\mathrm{d}}^{10}5{\mathrm{s}}^{2}5{\mathrm{p}}^3 \end{gathered}$$
The element antimony, Sb (metalloid) has the largest atomic radius.
