 * Discovery:** Sir William Ramsey, M.W. Travers 1898 (England)
 * Electron Configuration:** [He]2s22p6
 * Word Origin:** Greek //neos//: new
 * Isotopes:** Natural neon is a mix of three isotopes. Five other unstable isotopes of neon are known.
 * Neon Properties:** The melting point of neon is -248.67°C, boiling point is -246.048°C (1 atm), density of gas is 0.89990 g/l (1 atm, 0°C), density of liquid at b.p. is 1.207 g/cm3, and valence is 0. Neon is very inert, but it does form some compounds, such as with fluorine. The following ions are known: Ne+, (NeAr)+, (NeH)+, (HeNe)+. Neon is known to form an unstable hydrate. Neon plasma glows reddish orange. The discharge of neon is the most intense of the rare gases at ordinary currents and voltages.
 * Uses:** Neon is used to make neon signs. Neon and helium are used to make gas lasers. Neon is used in lightning arrestors, television tubes, high-voltage indicators, and wave meter tubes. Liquid neon is used as a cryogenic refrigerant, as it has over 40 times the refrigerating capacity per unit volume than liquid helium and over three times that of liquid hydrogen.
 * Sources:** Neon is a rare gaseous element. It is present in the atmosphere to the extent of 1 part per 65,000 of air. Neon is obtained by liquefaction of air and separation using fractional distillation.

Neon colors can be anywhere, from your phone/phone case to a sign that you see at a mall, or a grocery store.

By Van

Neon is a very popular gas used in signs, and displays. "Neon light" is create when the gas is combine with lights going into the tube, it follows this light pattern in a way that, even a small amount of light can turn the entire tube shocking colors.
