The Fascinating Uses of Neon

Neon is a noble gas known for its low reactivity and stable closed shell configuration. Discovered in 1898, it is recognized for its bright red emission spectrum. Despite being rare on Earth, neon is abundant in the universe. It is widely used in neon lights and signage, particularly in places like Times Square. Additionally, neon serves as a cryogenic refrigerant, useful in cooling systems and preserving materials. While helium is often used as an alternative due to its lower cost, neon remains valuable for its unique properties.
