Neon is a chemical element with symbol Ne and atomic number 10. It is in group 18 (noble gases) of the periodic table. This was discovered along with krypton and xenon. Neon is a colorless, odorless, inert monatomic gas under standard condition, with about two-thirds the density of air. Atomic Number of Neon Atomic Number of Neon is 10. Chemical symbol for Neon is Ne. Number of protons in Neon is 10. Atomic weight of Neon is 20.1797 u or g/mol. Melting point of Neon is -248,7 °C and its the boiling point is -246,1 °C.

What's in a name? From the Greek word for new, neos.
Say what? Neon is pronounced as NEE-on.
History and Uses:
Diatomic atoms molar mass. In molecule Diatomic molecules contain two atoms that are chemically bonded. If the two atoms are identical, as in, for example, the oxygen molecule (O 2), they compose a homonuclear diatomic molecule, while if the atoms are different, as in the carbon monoxide molecule (CO), they make up.
Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. Like krypton, neon was discovered through the study of liquefied air. Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth's atmosphere is neon.
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 highly inert and forms no known compounds, although there is some evidence that it could form a compound with fluorine.
