Neon is a chemical element; it has symbol Ne and atomic number 10. It is the second noble gas in the periodic table. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air.
Jun 6, 2024 · Neon, chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colorless, odorless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth’s atmosphere and trapped within the rocks of Earth’s crust.
So Neon might have lost some of its unique lustre here on Earth, but further away, it has helped reveal some secretes of the most important glowing object for our planet, the Sun. Solar particles or solar wind also contain Neon in the ratio of two neon isotopes in Moon rock samples, rocks that get blasted by the solar wind for billions of years ...

Neon is the 10th element in the periodic table and has a symbol of Ne and atomic number of 10. It has an atomic weight of 20.1797 and a mass number of 20. Neon has ten protons and ten neutrons in its nucleus, and ten electrons in two shells.
Jun 26, 2024 · Neon is a noble gas with the chemical symbol Ne and atomic number 10, known for its distinct reddish-orange glow in neon lights. It’s inert, colorless, odorless, and tasteless in its natural state, found in small amounts in the Earth’s atmosphere.
Jul 3, 2019 · Neon is the element best-known for brightly-lit signs, but this noble gas is used for many other purposes. Here are neon facts: Neon Basic Facts. Atomic Number: 10. Symbol: Ne. Atomic Weight: 20.1797. Discovery: Sir William Ramsey, M.W. Travers 1898 (England) Electron Configuration: [He]2s 2 2p 6. Word Origin: Greek neos: new.
Aug 10, 2012 · The story of neon begins in the 1890s, with Scottish chemist Sir William Ramsay. Best known as the codiscoverer of four of the noble gases (neon, argon, krypton, and xenon), Ramsay also isolated and characterized helium and radon, the other two noble gases, winning the Nobel Prize for his efforts.
Neon (from the Greek word neos, meaning "new") is the second lightest of the noble gases . It forms no stable compounds with other elements. Discovered in 1898 by Sir William Ramsay and Morris Travers during their experiments with liquid air, neon accounts for 18 millionths (18 ppm) of the volume of Earth's atmosphere.
May 1, 2013 · Neon is the fifth most common element in the universe, and is formed by helium and oxygen nuclei fusing. It is found both in our atmosphere and in Jupiter's. On Earth it is found in tiny quantities in the air (18 ppm), sea water (0.2 ppm), and in the crust (70 ppt).
