Neon is chemically inactive
Lighting, to make neon signs, high-voltage indicators, televisions tubes, refrigerant and gas lasers
There are no common compounds for the element neon
How was it discovered?
In 1898, Sir William Ramsay founded the element
How was it obtained?
Liquid air: air that has been cooled to very low temperatures, so that it has condensed into a pale blue, mobile liquid
neon is colorless, odorless and tasteless
this is a rare, gaseous element
$33 per 100 grams
fourth most abundant element in the universe
a rare, inert gaseous element occurring in the atmosphere to the extent of 18 parts per million and obtained by fractional distillation of liquid air. it's colorless but glows a reddish-orange in electrical discharge and is used in displays and indicators
Neon is an atmospheric gas that imposes no threat to the environment and can have no compounds, no known to ecological damage caused by neon.
Neon forms in stars when they reach a mass equivalent to eight of more than our suns mass.
