NEON

HISTORY OF NEONNeon was discovered by Sir William Ramsay,a Scottish chemist,and Morris M. Travers,an English chemist. It was discovered in London,England, 1898 when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off.

The largest use for neon gas is in advertising signs. Neon is also used to make high voltage indicators and is combined with helium to make helium-neon lasers. Liquid neon is used as a cryogenic refrigerant.Neon is used in vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, and helium–neon lasers.

Physical Properties-Neon glows when a high electrical voltage is passed through it.Chemical Properties-Neon does not form compounds with other substances and is oderless.Melting Point:-249 cBoiling Point:-246.7 cDensity: 0.0009 g/cm³Color:Neon is colorlessType Of Element:Noble Gases

has about two-thirds the density of air

If you could gather all the neon from the rooms in a typical new home in the United States, you would get 10 liters (2 gallons) of neon gas

If you pass an electric charge through neon, it glows red

has no stable compounds

If you could gather all the neon from the rooms in a typical new home in the United States, you would get 10 liters (2 gallons) of neon gas.

Neon forms in stars

Neon is the second lightest noble gas after helium.

One quart of neon can light up 200 - 300 feet of glass tubing.

Neon gas in a light, can last for 15 years, without going off

Name means "new one"

Neon forms in stars with a mass of eight or more Earth suns
