Inert gas facts for kids
An inert gas is a gas that does not usually react chemically with other things. Examples of inert gases are neon and helium.
An inert gas made of only one element is called a noble gas. Inert gases can also be made of more than one element. They can be gases of molecules or mixtures of gases of elements.
Inert gases are used in several ways. A gas made from nitrogen is used to keep vegetables from spoiling when they are transported. Other inert gases are used in welding. They are put into gasoline tanks to help prevent explosions.
