- a very common element in the universe but rare on Earth
- gives a distinct reddish-orange glow when used in discharge tubes and neon lamps
- is commercially extracted from air, in which it is found in trace amounts
- is the second-lightest n
- has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen (on a per unit volume basis)
- is the fifth most abundant chemical element in the universe by mass, after hydrogen, helium, oxygen, and
- is used in vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, light signs, and helium-neon lasers
- liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more extreme liquid helium refrigeration
