Solution

Nobel Gas: Noble gases, also known as inert gases are the elements that belong to group 18 of the modern periodic table. These elements exist in the gaseous phase.
The Octet rule: The octet rule states that every atom in order to attain stability is to be filled with "8" electrons in their outermost electron shell.
As the number of electrons in the outer shell of the most stable or inert atoms is 8.
They are known to possess extremely low chemical reactivity hence the name inert gas.
$Neon (Ne)$ gas is also an example of Nobel gas or inert gas.
The electronic configuration of $Neon (Ne)$ is ${}_{10}{Ne} : 2 (K), 8 (L) .$
Therefore, $Neon (Ne)$ gas does not combine with other elements to form a compound.
