What is the formula for argon?

Answer 1

Argon (gas) is a naturally occurring element. Almost 1% of the earth's atmosphere is argon, being the third most abundant gas in the atmosphere after nitrogen and oxygen.

The chemical symbol for argon is Ar, and the most common form is the stable isotope 40Ar.

Interestingly, naturally occurring potassium (isotope 40K), having a half-life of 1.25 × 109 years, actually decays to 40Ar and Calcium. So, if you wait long enough, argon gas (40Ar) will actually make itself from potassium!
