  • Description In 1898, Dr William Ramsay and Morris M. Travers, a Scottish scientist and a British scientist, respectively, discovered neon as a condensation product in liquefied air, as in a process similar to that used to collect neon today. Neon’s use in lighting evolved from discoveries that gases under low pressure conduct electricity. When some flowing electrons collide with residual gas in an evacuated glass tube, the resulting ions emit light as they return to their nonexcited state. The color of the light depends on the residual gas; neon gas produces a red color and argon, another inert gas often used in tubes (which are frequently and incorrectly called neon lights), produces a blue color. These two basic colors are often modified into many different hues by the addition of such elements as mercury and cadmium. The neon found on the Earth is considered to be primordial in origin. Most of the neon is sequestered in the Earth’s rocks or dissolved in water, with small amounts escaping into the atmosphere during geologic weathering. The escaped gas is slowly lost into space faster than it is replenished. Consequently, neon constitutes only a small part (0.0018%) of the Earth’s atmosphere, although this element is estimated to be the fourth most abundant in the universe.
  • Physical properties Neon is a monatomic atom that is considered relatively inert. It does not even combinewith itself to form a diatomic molecule, as do some other gases (e.g., H2 and O2). Duringthe 1960s it was discovered that the noble gases are not really inert. Neon and the heaviernoble gases (Kr, Xe, and Rn) can form compounds when in an ionized state with some otherelements. For example, neon can form a two-atom ionized molecule of NeH+. Neon has alsobeen forced to form a compound with fluorine. Neon’s melting point is –248.59°C, its boiling point is –246.08°C, and its density is0.0008999 g/cm3.
  • Uses Gas in neon light tubes; ingredient of gaseous fillers for antifog devices, warning signals, electrical current detectors, high-voltage indicators for high-tension electric lines, lightning arresters, wave-meter tubes; in Ne-He lasers; in mixtures with He and Ar in Geiger counters. Liquid as cryogen to produce low temperetures. The most common use of neon is in the manufacture of luminescent electric tubes andspecialty high-voltage indicators. Neon is placed in enclosed glass tubes of various shapes withan electrode at each end. When neon gas is ionized by the passing of a high-voltage, low-ampselectrical current through it, a bright red color is produced. Other noble gases produce differentcolors, and they can be mixed. Unlike incandescent lamps, neon tubes can be bent andformed into unique shapes, including forming words and images for commercial advertisingand signage. Neon is primarily used in luminous tubes (vacuum electric discharge tubes), airplane beacons, helium–neon lasers, highvoltage indicators, cryogenic refrigerant, and laboratory experiments. Other noble gases, especially helium and xenon, have been found to be useful in anesthesiology and for neuroprotection, but the few studies using neon have not confirmed its usefulness in clinical medicine.
