where is argon found on earth
Argon is the most abundant of the noble gases in the Earth's atmosphere. It constitutes nearly 1% (0.94%) of the volume of air making it the third most abundant element in air after nitrogen and oxygen.Argon is also found in small traces in the Earth's crust and ocean waters.Argon is usually produced from liquid air as a byproduct of the production of nitrogen and oxygen.rgon has three isotopes that are stable including argon-36, 38, and 40. By far the majority (over 99%) of argon found naturally on Earth is argon-40. The most common argon isotope in the universe is created by stars and is argon-36.
