Uses: Neon is used glow lamps, electron tubes, signs, plasma studies, fluorescent starter tubes, cryogenic refrigeration and gas lasers. Neon is a colorless, odorless, and tasteless monatomic gas, belonging to the Group VIIIA elements, called noble gases. Neon, the name of which is derived from the Greek word neos, new, is present in some minerals, but its only commercial source is the atmosphere, of which it comprises 18 parts per 1,000,000 by volume.
A neon sign is a lighting display made of glass tubes that have been filled with a gas and bent into the shape of letters or decorative designs. When a high-voltage electrical current is passed through the gas, the tubes emit light. Although neon gas was originally used in these signs, several other gases are also used. These gases, along with different tints and phosphor coatings for the glass tubes, produce a spectrum of over 50 brilliant colors.
