* Atmosphere: Argon is the third most abundant gas in the Earth's atmosphere, making up about 0.93% of the air we breathe. It's a noble gas, meaning it doesn't readily react with other elements.
* Underground: Small amounts of argon can be found trapped in underground formations, like natural gas deposits.
* Minerals: Some argon can be trapped within certain minerals, like potassium-rich rocks.
* Water: Argon can dissolve in water, but in very small amounts.
It's important to note that while argon is abundant in the atmosphere, it's not extracted from the air for everyday use. Instead, it's produced as a byproduct of the industrial production of oxygen and nitrogen.
