80% nitrogen, 20% oxygen
however it's really 79% plus some decimals of nitrogen and 21% oxygen and a little moisture.
But if the question is only looking for a basic answer, just use the top answer.

The ratio of nitrogen to oxygen in the air is approximately 78% nitrogen and 21% oxygen. These two gases are the main components of Earth's atmosphere, with nitrogen being the most abundant.
The ratio of nitrogen to oxygen in Earth's atmosphere is approximately 4:1. This means that nitrogen makes up about 78% and oxygen makes up about 21% of the gases in the air.
Nitrogen will form a compound with oxygen in a 1:1 ratio, creating nitrogen dioxide (NO2).
The ratio of oxygen to nitrogen in Earth's atmosphere is approximately 1:4, with oxygen making up about 21% and nitrogen about 78%. This ratio can vary slightly depending on factors such as altitude and location.
No, the ideal ratio of oxygen to nitrogen in the air is already balanced to support human life. Increasing the oxygen concentration can be harmful as it may lead to oxygen toxicity, while decreasing the nitrogen concentration can lead to nitrogen narcosis.
Nitrogen dioxide (NO2) consists of one nitrogen atom and two oxygen atoms, giving it a ratio of 1:2 between nitrogen and oxygen. This means that for every 1 nitrogen atom, there are 2 oxygen atoms in a molecule of nitrogen dioxide.
