Noble gases are inert because they have a complete outer shell.
They do not react with any substance found in nature.
They are used in filling light bulbs to maintain pressure inside and outside the bulb.
They are light and monoatomic.
Helium is the exceptional among the noble gases because it has only one shell (K shell) and 2 electrons in it (hence, complete outer shell) but other noble gases have 8 electrons in their outer shell.
