There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen

Is the air on moon breathable?
No, because people can only breathe with Earth air (which mainly consists of Nitrogen and Oxygen), and moon atmosphere has no Nitrogen or Oxygen.
What is the main component of Mars' atmosphere?
Mars has an atmosphere, though it is different than our atmosphere here on Earth. The atmosphere of Mars is thin, cold, and dry and contains much less oxygen than the atmosphere of Earth. The oxygen content of the Martian atmosphere is only 0.13 percent, compared with 21 percent in Earth's atmosphere. Carbon dioxide makes up 95.3 percent of the gas in the atmosphere of Mars. It also contains nitrogen and argon and very small amounts of water and methane. Additionally, the atmospheric pressure on Mars is only about 1/100 that of Earth's!
Which planet's atmosphere has only 21 percent oxygen?
The oxygen in Earth's atmosphere comes from photosynthesis, which is carried out by plants and algae. Earth is the only planet known to have life, which is the only way we know of that would cause a planet to have an oxygen-rich atmosphere. Oxygen can form from the chemical breakdown of water via sunlight, but only in trace amounts.
What are the most common gases in the atmosphere?
The troposphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is composed of particulates and trace gases, including water vapor.
Why would astronaut have a hard time breathing on the moon?
We need oxygen to survive. It has an atmosphere but it just does not have any oxygen. The very thin atmosphere, known as an exosphere, contains helium, argon, neon, ammonia, methane and carbon dioxide. And if your talking about an oxygen cylinder, it has limited oxygen so you can only breathe for sometime but they have enough oxygen to stay for days
How do we intake only oxygen from the atmosphere?
We dont, we breath nitrogen and oxygen...but only the oxygen gets used by our bodies.
What is a component of the earths atmosphere?
Significant components of the Earth's atmosphere include nitrogen, oxygen, and carbon dioxide.
Is the air on moon breathable?
No, because people can only breathe with Earth air (which mainly consists of Nitrogen and Oxygen), and moon atmosphere has no Nitrogen or Oxygen.
What gases from the earths atmosphere are most abundant?
We know that nitrogen (at about 78%) and oxygen(at about 20 %) are the most abundant gases in the atmosphere. By inspection, it's obvious that there is only a couple of percent for all the other gases combined.
What is the main component of Mars' atmosphere?

Are CO2 and Oxygen the only gasses on earth?
No, they're not. In fact, about 78% of the Earth's atmosphere is nitrogen.
What planet has a nitrogen- oxygen atmosphere?
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Is oxygen the only gas found in Earth's atmosphere?
No there is also nitrogen (78%), carbon dioxide and other rare gases in the atmosphere.
Does argon contributes 1 percent of current global warming?
no only oxygen and nitrogen
Which of the 8 major planets has a mostly nitrogen atmosphere?
Only one. The one we walk, talk and live on. 78% nitrogen, 21% Oxygen.
Is phosphorus cycled through the earths atmosphere?
phosphorus is not cycled through the earth's atmosphere
What are the two most abundent gases in your atmosphere?
Nitrogen and Oxygen. I can only assume by the wording of you question that you are either an astronaut, on a ventilator or reside on some crazy distant planet.
