The elements belonging to group 8 of the periodic table are known as the noble gases. They are also known as inert gases due to the fact that their outermost shell is completely filled. This characteristic makes them completely unreactive.
The noble gases are odorless and colorless in nature and are monoatomic gases. According to the modern IUPAC ruling, the noble gases are assigned group 18. The noble gases are able to react only under extreme conditions of temperature and pressure.
Examples of Noble Gases:
Helium, neon, argon, krypton, xenon, and radon are naturally occurring noble gases. Helium is used by deep-sea divers in order to prevent the toxicity of oxygen, nitrogen, and carbon dioxide, and argon is employed in incandescent bulbs.
