Neon Properties




Neon is a inert noble gas under standard conditions. It is commercially extracted from air, in which it is found in trace amounts. It is often used in signs and produces an unmistakable bright reddish-orange light. It is used in vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, and helium-neon lasers.
