There is approximately 21 % oxygen in our air.
Nitrogen makes up 78% of the atmosphere, not 98%.
Nitrogen is: at around 78% of the atmosphere it is the most abundant gas in the atmosphere. Also there is 21% of Oxygen and the rest is made up of 1% of other gases.
The Earth's atmosphere is made up almost entirely of two gasses, oxygen & nitrogen. It's 21% oxygen and 78% nitrogen. So, these two make up 99%. The remaining 1% is a collection of other gasses.
My atmosphere is the same as your atmosphere since we all live on the same planet. Oxygen makes up about 19.5% of the atmosphere.
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.

The atmosphere.
Oxygen (O2)
Earth's atmosphere is made up of the following main gases: nitrogen, oxygen, carbon dioxide, and argon. There also are minute amounts of neon, helium, and methane. The atmosphere contains about 78 percent nitrogen, 20 percent oxygen, 0.93 percent argon, and 0.039 percent carbon dioxide..
Oxygen
A tiny fraction of a percent. Mars has an extremely thin atmosphere, and what it does have is mostly Carbon Dioxide.
No - out atmosphere is made up of approximately 78% Nitrogen, 21% Oxygen and 1% other gasses.
The percentage of oxygen in the atmosphere is approximately 21%. Nitrogen makes up 78% and the last 2% percent is a mixture of various different gases, mostly argon.
