Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and …

From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2, and trace gases. Because water vapor is highly variable geographically, it’s excluded from this total.

2025年2月26日 · Argon constitutes 1.288 percent of the atmosphere by weight and 0.934 percent by volume and is found occluded in rocks. Although the stable isotopes argon-36 and argon-38 make up all but a trace of this element in the universe, the third stable isotope, argon-40, makes up 99.60 percent of the argon found on Earth. (Argon-36 and argon-38 make up ...

Argon is the third most abundant gas in our atmosphere, though it makes up only a little less than 1% of the total amount of gases in the air. Argon is an inert gas, which means it doesn’t react or interact with other substances.

Argon makes up 0.94% of the Earth’s atmosphere and is the third most abundant atmospheric gas. Levels have gradually increased since the Earth was formed because radioactive potassium-40 turns into argon as it decays. Argon is obtained commercially by the distillation of liquid air.

Argon makes up 0.93% of the earth's atmosphere, making it the third most abundant gas. Argon is obtained from the air as a byproduct of the production of oxygen and nitrogen. From the Greek argos, inactive. Its presence in air was suspected by Cavendish in 1785, discovered by Lord Raleigh and Sir William Ramsay in 1894.

2012年12月12日 · Argon accounts for nearly 0.93% of the atmosphere and the concentration of argon in the Earth's crust is around 4 ppm. Argon has 24 known isotopes with mass numbers from 30 Ar to 53 Ar. Of these, three isotopes, 36 Ar, 38 Ar, and 40 Ar are stable and occur naturally. There are also six radioactive isotopes of Argon.

2025年1月5日 · Argon is the third most abundant gas in Earth’s atmosphere, after nitrogen and oxygen. It is a colorless, odorless, and tasteless gas that is not harmful to humans or the environment. Greenhouse gases are gases that trap heat in the Earth’s atmosphere, causing the planet to warm.

2023年9月25日 · Argon is the third most abundant gas in the Earth's atmosphere, making up 0.934% of the air we breathe. It is a noble gas, meaning it does not react with most other elements, and it is classified as a non-toxic and non-irritant, making it safe for human exposure.

While nitrogen (78% of the atmosphere) and oxygen (21% of the atmosphere) reign supreme in Earth's atmosphere, another gas stands out with its surprising abundance: argon. Making up almost 1% of the air we breathe, argon is 25 times more prevalent than all other non-oxygen/nitrogen gases combined.
