argon gas

Argon is a noble gas, meaning it’s a colorless, odorless, and inert (non-reactive) element found in small amounts in the Earth's atmosphere. It’s often used in lighting, such as in incandescent and fluorescent bulbs, because it doesn’t react with the filament, helping it last longer. Argon also provides an inert environment in welding and metal manufacturing, preventing oxidation and contamination. Due to its stability, it’s safe and valuable in various industrial and scientific applications, contributing to processes where a non-reactive atmosphere is essential.
