What is Neon?

  • Neon is a chemical element with the symbol Ne and the atomic number 10.
  • This element Can be found in nature as a colorless gas.
  • Electric discharge emits a reddish-neon color, which shows that why neon lamps have a wide range of advertising uses.
  • Neon has 40 times the cooling properties of liquid helium and 3 times the liquid hydrogen, and it’s also used in the refrigeration industry.
  • Although neon is an inert gas in many practical cases, in combination with fluorine in the laboratory, it produces interesting colored compounds.
  • The above action suggests that the neon compound exists naturally; However, the evidence says that this hypothesis may be true or may not be true.
  • Neon is a very dangerous and deadly gas.
  • This gas can cause severe suffocation.
