Neon

In the 1770's, chemists thought there were only Nitrogen and Oxygen in the air. Then they discovered Argon, and with that, they made up 99.966% of air. They couldn't figure out what the other 0.034% was... until Ramsay and Travers found the element Neon.

- it can be absorbed when breathing-when taken in by inhalation, neon will evaporate very quickly., causing a very high risk of suffocation. It can also cause dizziness, nausea, loss of conciousness and death.-when exposed on skin and eyes, it can cause a frostbite-because neon is a inert gas, it is classified as a simple asphyxiant.Neon has no environmental effects because it is chemically unreactive and forms no compounds.

Neon is the fifth most abundant element in the universe. 0.0018% of the Earth's atmosphere is neon.The abundance in the earth's crust is 3×10-7%

NeonAtomic Number: 10Atomic Mass: 20.1797Mass Number: 20Melting Point: -248.59°C Boiling Point: -246.08°C.Density: 0.901g/cubic centimetre. Protons: 10Electrons: 10Neutrons: 10Group: 18 (Noble Gas) It is colorless, odourless, and tasteless.

Neon

-Neon forms in stars with a mass of eight or more Earth suns. Near the end of their lives, the stars enter a phase called the carbon burning phase, resulting in making oxygen, sodium and maganese. -Neon has no stable compounds.-Neon doesn't react with water, but it dissolves slightly to the extent of 10.5 cm3 at 20°CThe three isotopes for neon are: neon-20, neon-21, and neon-22.

Neon was discovered by William Ramsay and Morris Travers (who also discovered Krypton) in the United Kingdom in 1898. They heated a sample of gas and found spectral lines that were new to them. It was Neon. It's name comes from the Greek word "neos," meaning "new." It is considered a non-metal, and a noble gas. (group 18) It is chemically unreactive and forms no compunds.

Neon

Who Discovered it?

Abundance

Neon is mostly known for advertising signs.It is also used to make helium-neon lasers by combining neon and helium. These lasers are used in eye surgery to remove eye cataracts (they save your eyes) Neon is also used to make other lasers used in industries and medicine. It is used in vacuum tubes, high-voltage indicators, lightning arrestors and water meter tubes.When neon is liquified, it can be used as a cryogenic refrigerent. Without neon, we wouldn't be able to watch tv.We wouldn't be able to do eye surgery and most other laser related tasks. You would be surprised how much we wouldn't be able to do without neon.
