| While experimenting on liquid air, Sir William Ramsay and Morris Travers discovered neon in 1898. |
| The scientists had only recently discovered krypton prior to their discovery of neon, and would discover xenon shortly afterwards. |
| Neon is left over, along with krypton and xenon, when nitrogen, oxygen, argon, and carbon dioxide are removed from air. |
| Trace amounts of neon are found in the Earth's atmosphere. |
| The concentration of neon in the atmosphere is about 1 part in 55,000, or 18.2 ppm by volume or 1 part in 79,000 of air by mass. |
| It can be created commercially as the byproduct of liquefaction of air. |
| Neon is about two-thirds as dense as air. |
| Neon is the second lightest inert gas, as well as being the second lightest noble gas after helium. |
| It has three stable isotopes. |
| Georges Claude began creating neon lighting in 1902, as he had surplus neon leftover as a by product of his air liquefaction company. |
| In 1910, Georges Claude attempted to create interior home lighting using neon lights in vacuum tubes, but homeowners did not accept the idea due to their color. |
| Neon has over forty times the refrigerating ability of liquid helium and three times that of liquid hydrogen. |
| Neon is the fifth most abundant chemical element in the universe, following behind hydrogen, helium, oxygen, and carbon. |
| Its mass abundance in the universe is about one part per 750. |
| Neon's rarity makes it fairly expensive, making liquid neon about 55 times more expensive than liquid helium. |
| While neon glows reddish orange in commercial signage, other noble gases create the other colors for neon signs. |
