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.
The identity of the gas in the tube determines the color of the glow. Neon emits a red glow, helium produces pale yellow, and argon yields blue. Mercury vapor also emits blue light, and sodium vapor emits yellow. The majority of neon signs contain either neon gas or a mixture of neon and mercury vapor.
