What is Neon?

  • Neon is reddish-orange colored in neon lamps and vacuum discharge tubes and second-lightest noble gas. It is less expensive refrigerant than helium in many applications. Its refrigerating capacity is 40 times more than liquid helium and three times to liquid hydrogen on per unit volume basis. It is a rare gas, and its molecules consist of a single Neon atom.
  • It is chemically inert gas and non-toxic in nature. There is no threat to the environment and has no impact since it’s nonreactive and does not form compounds. This element cause no ecological damage.
  • It can create exotic compounds with fluorine in laboratories, being an inert element. It also forms an unstable hydrate.

Uses of Neon

  • The reddish-orange colored neon lights are used in making advertising signs. It’s also utilized in these types of lights generally when many other gasses are needed to generate lights of different colors.
  • Other uses of neon include lightning arrestors, high-voltage indicators, television tubes and meter tubes.
  • Gas lasers are made with the help of neon and helium.
