Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. read more
The gas that makes Las Vegas shine is one of the nobles — the noble gases, that is. Neon is one of six elements, found in the rightmost column of the Periodic Table, that are inert. read more
The first neon signs were dubbed 'liquid fire' and people would stop in the street to stare at them, even in daylight, they glow visibly. These days neon is extracted from liquid air by fractional distillation and just a few tons a year of the abundantly available gas is enough to satisfy any commercial needs. read more
