Neon is found primarily in the universe and can be extracted from the Earth's atmosphere.
While neon is the fifth most abundant element in the universe, on Earth, it's relatively scarce. It exists in the Earth's atmosphere at a concentration of approximately 18 parts per million. Neon is commercially extracted from liquid air through a process called fractional distillation. This process separates gases based on their boiling points, resulting in a fraction containing both helium and neon, which can be further separated.
In summary, neon is found:
- Universe: Abundantly as the fifth most common element.
- Earth's Atmosphere: In trace amounts, extractable through fractional distillation of liquid air.
