Why helium neon and argon are called inert gases?

Noble Gases. They are helium, neon, argon, krypton, xenon, and radon.They were once called inert gases because they were thought to be completely inert—unable to form compounds.This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.
