If you could extract all the neon from a new home in the United States, you would have about 10 liters of the gas. Even though it's rare and expensive on Earth, there is a fair amount of neon in the average home.Because neon is rare in air, it's an expensive gas to produce, about 55 times more expensive than liquid helium. Neon is also found in diamonds and some volcanic vents. The sole source of neon is from extraction from liquefied air. Although neon is a rare gas in the Earth's atmosphere ( about 0.0018 percent by mass), it is the fifth most abundant element in the universe (one part per 750), where it is produced during the alpha process in stars. Neon is both rare and abundant, depending on where you're looking for it.Ramsay's son suggested the name for the new element, neon. When the krypton was gone, the remaining gas was found to emit a bright red light when ionized. The gases that escaped were identified as nitrogen, oxygen, argon, and krypton. Neon was discovered in a sample of liquid air. The name of the element comes from the Greek word "novum" or "neos," which means "new." British chemists Sir William Ramsay and Morris W.A possible exception is solid neon clathrate hydrate, which may be formed from neon gas and water ice at a pressure of 0.35–0.48 GPa. In fact, there are no known stable neon compounds, even though some other noble gases have been found to form chemical bonds. It belongs to the noble gas element group and shares the property with other elements of that group of being nearly inert (not very reactive). At room temperature and pressure, neon is an odorless, colorless, diamagnetic gas. The element is in group 18 of the periodic table, making it the first noble gas with a full octet (helium is lighter and stable with only two electrons). The first two valence electrons are in the s shell, while the other eight electrons are in the p shell. Because it has a stable octet for its outer electron shell, neon atoms have 10 electrons and no net electrical charge. There are three stable isotopes of the element, with atoms having 10 neutrons (neon-20), 11 neutrons (neon-21), and 12 neutrons (neon-22).
