These gases are called noble because they are very unreactive. Also:
- helium: from the Greek word helios with the meaning sun
- neon: idem with the mening of new
- argon: idem, with the meaning of inactive
- krypton: idem with the meaning of hidden
- xenon: idem, with the meaning of strange
- radon: the name is derived from radium emanation
They have completely filled valence orbitals and are chemically inert. since they don't react, they are considered to be noble.

Pure gas is not another name- inert gas is - although this is has been superseded by noble gas as chmical compounds have been discovered for the heavier noble gases since 1963.
