Composition of the Atmosphere Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

Argon Element Facts Source: Argon is produced when 40K present naturally in the earth’s crust undergoes radioactive decay to 40Ar. The argon makes its way into the atmosphere. Argon is produced commercially by fractional distillation of liquefied air with (for high purity argon) catalytic burning of left over traces of oxygen.

- What percentage of the air is argon? The element argon (atomic number 18) constitutes about 1% of the Earth's atmosphere by volume. Why is argon used in a lightbulb instead of air? The filament lasts for a long time because argon is inert and will not oxidize the filament even at high temperatures.

- Methane makes up just 0.00018 percent of the atmosphere, compared to 0.039 percent for carbon dioxide. (CO2 is roughly 200 times more abundant.) Yet scientists attribute about one-sixth of recent global warming to methane emissions; what methane lacks in volume it makes up for in potency.

Noble gases Of all the rare gases, argon is present in the greatest amount. It makes up about 0.9 percent by volume of Earth's atmosphere. The other noble gases are present in such small amounts that it is usually more convenient to express their concentrations in terms of parts per million (ppm). The concentrations of neon, helium, krypton, and xenon are, respectively, 18 ppm, 5 ppm, 1 ppm, and 0.09 ppm.

Argon - Ar Argon in the environment. In earth's atmosphere, Ar-39 is made by cosmic ray activity, primarily with Ar-40. In the subsurface environment, it is also produced through neutron-capture by K-39 or alpha emission by calcium. Argon-37 is produced from the decay of calcium-40, the result of subsurface nuclear explosions.

Dinosaur Breath A missing piece of this puzzle may have been discovered. There are indications that the cretaceous atmosphere may have been much richer in oxygen. Today, Earth's atmosphere contains about 77% nitrogen, 21% oxygen, 1% water vapor, 0.9% argon, and 0.03% carbon dioxide, with traces of about a dozen other gases.ut now there is evidence that the cretaceous atmosphere may have been very different. Samples of 80 million year old air have been analyzed. You well might ask how there could be samples of air trapped and preserved for 80 million years. One might say that nature has provided the sample bottle.

- The percentage of Argon in the atmosphere is 0.93% in volume. (0.934 to be more accurate-pip) The atmosphere is 0.934% argon by volume, so, a lot of argon. The earth's atmosp…here has a volume of about 3x1024 m3, which means that there are about 2.8x1022 m3 (5x1012 mi3) of argon in the atmosphere. The density of argon is about 1.77 kg/m3 so there are about 1.58 kg of argon in the atmosphere.

- Trace Gases. Most of our atmosphere is made up of nitrogen (78% by volume) and oxygen (21% by volume). The remaining 1% of the atmospheric gases are known as trace gases because they are present in such small concentrations. The most abundant of the trace gases is the noble gas argon (approximately 1% by volume). Noble gases, which also include neon, helium, krypton and xenon, are very inert and do not generally engage in any chemical transformation within the atmosphere.

Astro 10 Study Set Earth's current atmosphere, the 3rd' Earth has had, is composed of nitrogen (78%), oxygen (21%), argon (1%), water (0-4%), carbon dioxide (small percent), and other trace gasses. The major difference between the second and the third atmospheres is the lack of carbon dioxide and the abundance of oxygen.

atmosphere We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth’s atmosphere. Other planets and moons have very different atmospheres, and some have no atmospheres at all.
