Overview of Neon
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. Neon, for example, has an atomic number of 10, which means that the number of protons in the nuclei of all neon atoms is 10; however, 90% of the neon atoms in nature have 10 neutrons present in their nuclei while 10% of the atoms have 12 neutrons. Such atoms of constant Z but different A are called isotopes.
- Atomic Number: 10
- Group: 18
- Period: 2
- Series: Noble Gasses
Neon's Name in Other Languages
- Latin: Neon
- Czech: Neon

- French: Neon
- German: Neon - r
- Italian: Neo
- Norwegian: Neon
- Portuguese: Neônio
- Russian: Неон
- Spanish: Neón
- Swedish: Neon
Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital.

- 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.
