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.
Neon signs that use an argon/mercury gas mixture emit a good deal of ultraviolet light. When this light is absorbed by a fluorescent coating, preferably inside the tube, the coating (called a phosphor) glows with its own color.
