Helium gas is a non-toxic and non-combustible gas that is obtained from natural gas. Helium Gas was first detected in sun. Helium is widely used in the medical field to treat respiratory disorders and also used in general anaesthetics. It is available abundantly and is the second lightest gas seen. Since it is the lightest gas it is used in helium balloons.
