The Elements: Neon

Neon is a colorless gas that emits a bright orange-red glow when electrified. It belongs to the noble gases group, making it highly unreactive and existing as single atoms. While abundant in the universe, neon is rare on Earth, contributing to its cost. Despite this, neon is used commercially in helium-neon lasers and neon lights.
