What is Neon Element?

Neon is a chemical element with the symbol Ne and atomic number 10. It is a rare gaseous element found in the atmosphere, making up about 1 part in 65,000 of air. Neon is obtained by liquefaction of air and separated from it. This noble gas is colorless, odorless, and inert under standard conditions, exhibiting an orange-red glow when placed in an electric field. Neon has a stable atomic structure, preventing it from forming compounds with other elements, which makes it one of the inert elements. It is denser than air and is used in various applications.

Chemical Properties of Neon

Neon shows various chemical properties, which are:


  • Neon is primarily an inert element, exhibiting very low chemical reactivity.
  • It does not readily form compounds with other elements under normal conditions.

Exotic Compounds:

  • Although Neon is primarily inert, it can form exotic compounds with fluorine in laboratory settings.
  • The existence of natural neon compounds is uncertain.

Ions and Hydrate:

  • Neon can form ions like Ne+, (NeAr)+, (NeH)+, and (HeNe+) as observed through research.
  • Neon also forms an unstable hydrate.

Chemical Reactivity of Neon

Neon is known for its extremely low chemical reactivity, primarily due to its stable electron configuration. Due to the following reasons, it doesn’t participate in chemical reactions:


Neon dissolves slightly in water to a limited extent of about 10.5 cm3/kg at 20°C (293 K)

Electrons gain enthalpy and Ionization Energy

The electron gain enthalpy value for Neon is positive, indicating that it requires energy for Neon to gain an electron. This positive value is consistent with the general trend for Group 18 elements, where electron gain enthalpy values are positive. This characteristic contributes to Neon’s chemical inertness, as it is less likely to gain electrons due to the energy required for this process.

Neon has a high first ionization energy, which is required to remove the outermost electron from a neutral atom of Neon. This high ionization energy is attributed to Neon’s stable electron configuration and the strong attraction between its electrons and the nucleus. The stable electron configuration of Neon, with a complete outer shell electronic configuration, makes it difficult to remove an electron, thus contributing to its high ionization energy.

In terms of Chemical reactivity, Neon’s positive electron gain enthalpy and high ionization energy contribute to its minimal chemical reactivity, making it one of the least reactive elements in the periodic table.

Applications of Neon

Neon has various applications in different fields, which are:

  • Advertising Signs: Neon is extensively used in neon signs for advertising, creating vibrant and eye-catching displays.
  • Neon’s distinctive bright reddish-orange glow makes it a popular choice for signage.
  • High Voltage Indicators: Neon is utilized to make high-voltage indicators whose unique properties benefit this application.
  • Helium-Neon Lasers: Neon is combined with helium to produce helium-neon lasers, which find applications in various fields such as optics labs.
  • Cryogenic Refrigerant: Liquid Neon is an essential cryogenic refrigerant, offering efficient cooling capabilities in specific applications.

Facts about Neon

Neon, a noble gas, has several interesting facts associated with it:

  • Neon was first discovered in its elemental form in 1898 and quickly gained popularity for its use in neon signs and other applications.
  • Neon is a rare gas, constituting only about 0.0018% of Earth’s atmosphere.
  • The first neon light was displayed in 1910 by Georges Claude at the Paris Motor Show, marking the beginning of Neon’s widespread use.
  • Neon gets its name from the Greek word ‘neos,’ meaning new, and has unique properties that make it valuable in various industries.
  • Neon is primarily obtained through the fractional distillation of air.
  • Neon has a long lifespan, with neon tubes lasting approximately 30,000 hours.
