PureGases 

Pure gas may be made up of individual atoms (e.g. a noble gas like neon),

elemental molecules made fromone type of atom (e.g. oxygen),

or compound molecules made from a variety of atoms (e.g. carbon dioxide).

A gas mixture, such as air, contains a variety of pure gases.

What distinguishes a gas from liquids and solids is the vast separation

of the individual gas particles.

This separation usually makes a colorless gas invisible to the human observer.
