  • Atmosphere/p.p.m.: 18
  • Sun (Relative to H=1E¹²): 3.72E+07
• Sources of Neon:

  It can be prepared by liquification of air and separated from other elements by fractional distillation. Annual world production is around 1 ton.

• Uses of Neon:

  In a vacuum tube, neon glows reddish orange, thus, the invention of the neon lights. Neon has also been used to make lightening arrestors, voltage detectors and TV tubes.

• Additional Notes:

  While it is inert, there have been reports of it combining with fluorine. Neon may also form ions in combination with other noble gases (NeAr, HeNe, Ne₂ and with hydrogen (NeH). It also forms an unstable hydrate, so it is not nearly as inert as one might think.
