Argon

Argon is a colorless, odorless, and inert gas that makes up about 1% of the Earth's atmosphere. It belongs to the noble gases group, meaning it is very stable and doesn't easily react with other elements. Argon is commonly used in light bulbs to prevent the filament from burning out, and in welding to protect the weld area from atmospheric gases. Because it doesn't react easily, it provides a safe, inert environment for sensitive processes. Its stability and non-reactivity make it valuable in industries requiring controlled atmospheres, ensuring safety and quality in various applications.
