The most common isotope of Argon, 40Ar, accounts for just under 1% of the Earth's atmosphere. Most of this comes from the radioactive decay of Potassiom-40 in the Earth's crust.

Argon makes up about 0.93% of Earth's atmosphere by volume, which is equivalent to around 0.04% by weight.
Yes, the earths atmosphere has around 20% oxygen, but less than 1% argon.
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.
Nitrogen, Oxygen and Argon make up 99% of the atmosphere
1 percent of the earths atmosphere is made of the following: - Argon (0.93%) - Carbon dioxide (0.03%) - Neon> trace - Helium> trace - Methane> trace - Krypton> trace - Xenon> trace - Hydrogen> trace - Ozone> trace 21% of earths atmosphere is made of oxygen 78% of earths atmosphere is made of nitrogen
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
Argon makes up about .93 percent of the Earths atmosphere. Hope this helps! (:
These gases are nitrogen, oxygen and argon.
Earths atmosphere is 78% nitrogen,21%oxygen,0.9% argon,and 0.03% carbon dioxide with very small percentages of other elements
These gases are nitrogen, oxygen, argon, carbon dioxide.
