Neon is one of the noble gases on the periodic table of elements, noted for its red-orange glow in neon lights. It is a fascinating element with unique properties and multiple applications, from advertising and sign-making to its more scientific uses in the fields of medicine and research.
What is Neon?
Neon, symbolized as Ne, is the second-lightest noble gas, following helium. It is a colorless, odorless, and tasteless gas under standard conditions. Neon is abundant in the universe but rare on Earth, making up only about 0.0018% of the Earth's atmosphere by volume.
Discovery of Neon
Neon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers. They discovered the element in the residual air after oxygen and nitrogen had been removed. They were able to identify neon through its bright red emission spectrum, and it was named "neon," a word derived from the Greek "neos," meaning "new."
Uses of Neon
One of the most common uses of neon is in advertising signs. When a high-voltage electric current passes through the neon gas in glass tubes, the gas glows with a bright, fiery light, which is perfect for illuminating signs and advertisements.
Neon is also used in vacuum tubes, high-voltage indicators, lightning arrestors, wave meter tubes, television tubes, and helium-neon lasers. In a more scientific setting, liquid neon is used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more extreme liquid helium refrigeration.
Conclusion
Neon, though not commonly found on Earth, plays an integral part in our modern lives. From the bright, colorful signs that light up our city streets to its role in scientific research and technology, neon continues to be a vital element in our world.
