Facts about Neon
Of all the rare gases, neon has the most intense discharge at normal voltages and currents.
Neon and helium may be used together to make a type of gas laser called a helium-neon laser.
Neon (chemical symbol Ne, atomic number 10) is the fourth most abundant chemical element in the universe, but it is just a trace element in the air.
Neon has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen (on a per unit volume basis).
Neon is less dense than air and is the second-lightest noble gas, after helium.
The word "neon" has become a generic term for these types of lights, although many other gases are used to produce different colors of light.
Consequently, the main use of neon is to make flashy signs for advertising.
Neon (from the Greek word ????, meaning "new") was discovered by Scottish chemist William Ramsay and English chemist Morris Travers in 1898, during their studies of liquefied air.
The reddish-orange color that neon emits in neon lamps is widely used for advertising signs.
Uses: Neon is used glow lamps, electron tubes, signs, plasma studies, fluorescent starter tubes, cryogenic refrigeration and gas lasers. Neon is a colorless, odorless, and tasteless monatomic gas, belonging to the Group VIIIA elements, called noble gases.
Neon is a rare atmospheric gas and as such is non-toxic and chemically inert. Neon poses no threat to the environment, and can have no impact at all because it's chemically unreactive and forms no compounds. No known ecological damage caused by this element.
Although neon is the forth most abundant element in the universe, only 0.0018% in volume of the earth's atmosphere is neon. ... Neon is a rare gas that is found in the Earth's atmosphere at 1 part in 65,000. Health effects of neon. Routes of exposure: The substance can be absorbed into the body by inhalation.
The largest use of neon is in making the ubiquitous 'neon signs' for advertising. In a vacuum discharge tube neon glows a reddish orange colour. ... Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant.
Neon is the fourth most abundant element in the entire universe, behind hydrogen, helium and oxygen. However, it is considered very rare on Earth as it can mainly be found in the atmosphere, which consists only 0.001818% of Neon in volume.May 7, 2015
Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.
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 a member of the noble gas family. ... The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon.
The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (red), helium (yellow), carbon dioxide (white), and mercury (blue).
