Answer:
Option-A (XY)
Explanation:
In this problem one should focus on the number of valence electrons present in each atom. Remember that in lewis structure the dots on an atom always show the valence shell electrons. In given statement;
The,
X has one valence electron. It means that it can loose this single electron to attain the noble gas configuration i.e.
X° → X⁺ + 1e⁻
Similarly,
Y have seven valence shell electrons. Therefore, in order to complete the octet this atom will gain one electron i.e.
::Y:° + 1 e⁻ → Y⁻
Hence, we can conclude that X got stabilized by losing one electron and Y got stabilized by gaining one electron therefore, only one of each is required to form an ionic compound i.e.
<h3>
X⁺ + Y⁻ → XY</h3>
