Argon (Ar) is a colorless, odorless noble gas. It comprises nearly 1% of Earth's atmosphere and is commonly used in welding, lighting, and preserving materials due to its chemical inertness.

/ˈɑːrɡɒn/

Argon is derived from the Greek word 'argos' meaning 'idle' or 'lazy', referring to its inertness.

Argon is a gas that's all around us, making up almost 1% of the air we breathe and it doesn't react with other stuff.
