Consider elements $x$ and $Y$ :

Element $x$ has the highest $($most exothermic$)$ first electron affinity in its period; the ground state electron configuration of its most common ion is: $[Kr]5s^{2}4d^{10}5p^6$

Element $Y$ is the second largest atomic radius in its period; its valence electrons are in orbital$($s$)$ that have $n=6.$

What is the most stable compound formed when elements $x$ and $Y$ are combined?

a$.Ba{I}_2$

b$.CdB{r}_2$

c$.SrB{r}_2$

d$.$ SrTe

e$.Te{I}_2$
