    4. Ne or Neon.


    Neon light is visible from very long distances even in heavy fog during winter season.

    Neon gas is represented by symbol ‘Ne’. It is among six elements presented in Zero Group (or group 18) of periodic table. Neon (and other elements of group 18) is an inert or noble gas because they are highly unreactive.
