| Neon is a colorless, odorless gas that comprises 18 parts per million of the air. Neon will not react with any other substance. It is produced from liquid air for ornamental lighting because it glows reed when an electrical discharge is passed through it. Neon is a rare gaseous element present in the atmosphere to the extent of one part in 65,000 of air. It is obtained by liquefaction of air and separated from other gases by fractional distillation. It has over 40 times more refrigerating capacity than liquid helium and more than three times that of liquid hydrogen. |
