It is a noble gas.
The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

Symbol (chemistry)

Neon is a chemical element with the symbol Ne and atomic number 10.

Argon

Arargon gas 40 Ar
It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.
It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv).

Xenon

It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in September 1898, shortly after their discovery of the elements krypton and neon.

Neon compounds

compounds of neonneon clathrateneonium
The compounds of neon currently known include ionic molecules, molecules held together by van der Waals forces and clathrates.
Neon compounds are chemical compounds containing the element neon (Ne) with other molecules or elements from the periodic table.

Krypton

Kr 81 Kr m 82 Kr
It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.
Neon was discovered by a similar procedure by the same workers just a few weeks later.

Neon lamp

neonneon bulbneon lights
Neon gives a distinct reddish-orange glow when used in low-voltage neon glow lamps, high-voltage discharge tubes and neon advertising signs.
The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode).

Neon sign

neonneon signsneon signage
Neon gives a distinct reddish-orange glow when used in low-voltage neon glow lamps, high-voltage discharge tubes and neon advertising signs.
In the signage industry, neon signs are electric signs lighted by long luminous gas-discharge tubes that contain rarefied neon or other gases.

Monatomic gas

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.
These are helium, neon, argon, krypton, xenon and radon.

Jupiter

JovianGioveplanet Jupiter
Even the outer atmosphere of Jupiter is somewhat depleted of neon, although for a different reason.
There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, and sulfur.

Geissler tube

Crookes tubesdischarge tubeselectrical gas-discharge" tube
Neon gives a distinct reddish-orange glow when used in low-voltage neon glow lamps, high-voltage discharge tubes and neon advertising signs.
It consists of a sealed, partially evacuated glass cylinder of various shapes with a metal electrode at each end, containing rarefied gasses such as neon, argon, or air; mercury vapor or other conductive fluids; or ionizable minerals or metals, such as sodium.

William Ramsay

Sir William RamsayRamsayRamsay Fellow
Neon was discovered in 1898 by the British chemists Sir William Ramsay (1852–1916) and Morris W. Travers (1872–1961) in London.
His work in isolating argon, helium, neon, krypton and xenon led to the development of a new section of the periodic table.

Neon lighting

In December 1910 Claude demonstrated modern neon lighting based on a sealed tube of neon.
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases.

Oxygen

OO 2 molecular oxygen
It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed. Although neon is a very common element in the universe and solar system (it is fifth in cosmic abundance after hydrogen, helium, oxygen and carbon), it is rare on Earth.

Nitrogen

NN 2 dinitrogen
It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.

Gas

gasesgaseousgaseous state
Thomson eventually concluded that some of the atoms in the neon gas were of higher mass than the rest.
A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).

Helium–neon laser

HeNe laserHe-Ne laserHe-Ne
The red emission line from neon also causes the well known red light of helium–neon lasers.
The gain medium of the laser, as suggested by its name, is a mixture of helium and neon gases, in approximately a, contained at low pressure in a glass envelope.

Helium

Hehelium IIsuperfluid helium
Although neon is a very common element in the universe and solar system (it is fifth in cosmic abundance after hydrogen, helium, oxygen and carbon), it is rare on Earth.
Helium is the second least reactive noble gas after neon, and thus the second least reactive of all elements.

Neon was discovered in 1898 by the British chemists Sir William Ramsay (1852–1916) and Morris W. Travers (1872–1961) in London.
Morris William Travers, FRS (24 January 1872 – 25 August 1961) was an English chemist who worked with Sir William Ramsay in the discovery of xenon, neon and krypton.

Isotope

Though not understood at the time by Thomson, this was the first discovery of isotopes of stable atoms.
Thomson channeled streams of neon ions through a magnetic and an electric field and measured their deflection by placing a photographic plate in their path.

Aluminium

This isotope is generated by spallation reactions on magnesium, sodium, silicon, and aluminium.
An aluminium atom has 13 electrons, arranged in an electron configuration of [Ne]3s 2 3p 1, with three electrons beyond a stable noble gas configuration.

Sodium

NaNa + sodium ion
This isotope is generated by spallation reactions on magnesium, sodium, silicon, and aluminium.
Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon.

Solar neon

The 20 Ne-enriched components are attributed to exotic primordial rare-gas components in the Earth, possibly representing solar neon.
Solar neon is neon that is transmitted to Earth as ions in the solar wind.

They were filled with a pure inert gas such as neon because mixtures made the output temperature-dependent.
