Neon (Greek neos meaning "new") was
discovered (1898) by the British chemists Sir William Ramsay and
Morris W. Travers. The reddish-orange color that neon emits in
neon lights is widely used to make advertising signs. "Neon"
is also used generically for these types of lights when in reality
many other gases are used to produce different colors of light.
Other uses: high-voltage indicators, lightning arrestors, wave
meter tubes, television tubes. Neon and helium are used to make
gas lasers.
