Argon

Ar

Jan. 2025 - Argon is an inert gas that makes up 1% of the air we breathe. Special equipment can isolate it. Pure Argon is used to preserve things that would normally react to air. When pure, it's also dangerous to breathe, because it doesn't have Oxygen, and it's slightly heavier than air.
