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>
That’s what I’m tryna figure out

If a large leak of refrigerant occurs such as from a filled cylinder in an enclosed area, the correct action that should be taken when no self-contained breathing apparatus is available would be to vacate the spill area and ventilate it. Leaving the area of the spill should be done as fast as possible to avoid suffocation of the refrigerant or other health effects like burns and irritations. Also, diluting it with air or ventilating it would make it less harmful to the people affected by the spill as it would be less harmful than being in its concentrated form.
Atoms are real even though they're invisible.
