what elements are present in the planets atmosphere?

Question

i need to find out what elements are in our atmosphere & the reason why there their & also which of these elements ure sucked from the sky for govenred use?

Answer 1

Please use the spell checker when posting questions. Your spelling is so atrocious that it is difficult to determine what you are asking.

The elements are
diatomic Nitrogen N2
diatomic Oxygen O2
Carbon combined with Oxygen CO2
Trace amounts of Argon, Xenon and perhaps some of the other rare gases as well Check a periodic chart.

As to the last part of your question I have no idea what you are talking about. If the government has perfected a way to get some useful element from the atmosphere more power to them. Whatever they are getting is a pollutant and we don't need it there.

Answer 2

Mostly nitrogen (N2) and oxygen (O2), with all the rest 1-2 percent (depends on humidity). You ask about "governed" use. The only atmospheric gas that the government controlled, to my knowledge, was helium (He), because of strategic use in dirigibles and weapons production, but most He is a byproduct of of natural gas production.
Many large hospitals own their own air liquefaction plants; it's fascinating to see it fractionated to produce O2 and N2.
"Why" is a human value judgment; "how" is easier to answer:
Most of the Universe is H2, but, because Earth is relatively small (compared to the Sun or Jupiter), it couldn't "pull in" the less dense gases in it's neighborhood. Look up escape velocity and the speed of hydrogen molecules at room temperature (a Gaussian curve describes the fraction in a speed range). The H2 got a way, the denser stuff condensed, and the remainder was air... until photosynthesis broke down CO2 into O2 and plants.

Answer 3

Nitrogen 78%; oxygen 21%; neon, argon, krypton, xenon. (Water vapor and carbon dioxide, if you count their elements as elements.) The reason that they're there is that they are there. The rise of green plant life billions of years ago altered the atmosphere to produce so so much oxygen. Nitrogen is taken from the atmosphere to make ammonia and nitrates for fertilizer. Oxygen is taken from the air for many uses, all of them oxidation. Argon finds use in steel making.

Answer 4

Its mostly made up of Nitrogen, Oxygen, and a Argon. The Nitrogen is there because it is the by-product of stars, Oxygen is there because it comes from the Carbon and water vapor molecules when they dissociate, and Argon gets there by way of cosmic rays! Fascinating!
