Nitrogen and oxygen together make up approximately 99% of Earth's atmosphere, with nitrogen accounting for about 78% and oxygen around 21%.
Nitrogen makes up roughly 80% of Earth's atmosphere (Oxygen makes up most of the remainder).
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
The atmosphere contains more nitrogen than oxygen. Approximately 78% of the atmosphere is nitrogen, while oxygen makes up about 21%. The remaining 1% consists of other gases like argon, carbon dioxide, and trace gases.
Nitrogen is more abundant in Earth's atmosphere, making up about 78% of the air. Oxygen makes up about 21% of the atmosphere.
Nitrogen makes up about 78% of Earth's atmosphere, while oxygen makes up about 21%. Therefore, nitrogen and oxygen together make up approximately 99% of the air we breathe.
The highest percentage in the Earth's atmosphere is nitrogen, at 78%. Then oxygen(21%) and CO2, 0.9%.
Oxygen makes up about 21% and nitrogen makes up about 78% of the Earth's atmosphere, adding up to a total of approximately 99%.

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.
The two main atmospheric gases are nitrogen and oxygen. The approximate percentage for nitrogen is 78% and oxygen's approximate percentage is 21%.
