Question

Why is xenon being a noble gas that compounds other elements?

Answer 1

Hint: We know that the noble gases are the elements that are present in group $18$ in the modern periodic table. They are also called as inert gases. It consists of helium, neon, argon, Xenon, krypton and radon.

Complete Step By Step Answer:
Xenon is the element which is located in the group $18$ according to the modern periodic table. It is also called a noble gas element. The noble gas elements are inert in nature which means they are very least reactive because they have a full valence shell of electrons which makes them chemically stable and unreactive. They do not form compounds when they combine with other elements.
But in the case of Xenon, it is a noble gas but still it can form compounds with other elements. This is so because the inner electrons of the xenon screen the outer electrons from the nucleus. Xenon is a heavier noble gas that has more electron shells than the lighter ones. The inner electrons of xenon shield the outermost electrons so they are less strongly attracted to the nucleus. These outer electrons become a target for the high electronegative atom. A highly electronegative element such as fluorine shares these electrons.
Let’s see a few examples of compounds formed by xenon are $Xe{F}_4$ and $Xe{F}_2$ .

Note:
Xenon is a large sized element due to this electronic attraction to the nucleus is weaker. It can react with the highly electronegative element i.e. fluorine. Hence, the valence electrons of xenon are attracted by the electronegative element which results in the formation of compounds.
