Nitrogen makes up about 80% of the Earth's atmosphere.
Nitrogen
The percentage of nitrogen in the atmosphere remains relatively constant due to a balance between nitrogen fixation and denitrification processes. Nitrogen fixation, performed by certain bacteria and industrial processes, converts atmospheric nitrogen into forms usable by living organisms. Conversely, denitrification processes return nitrogen to the atmosphere by converting nitrates back into nitrogen gas. This continuous cycle keeps nitrogen levels stable, despite various biological and geological activities.
The percentage of nitrogen in the atmosphere increased over time primarily due to volcanic outgassing and the release of nitrogen compounds from Earth's interior. As the planet cooled, these gases, including nitrogen, accumulated in the atmosphere. Additionally, nitrogen is relatively inert and does not easily react with other elements, allowing it to build up as other gases, like carbon dioxide and water vapor, were removed or transformed through processes like photosynthesis. Over geological timescales, this led to nitrogen becoming the dominant gas in the modern atmosphere.
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.
Hydrogen makes up about 0.000055% of Earth's atmosphere. It is much less abundant compared to other gases like nitrogen and oxygen.
The percentage of nitrogen in the Earth's atmosphere is about 78.
The highest percentage in the Earth's atmosphere is nitrogen, at 78%. Then oxygen(21%) and CO2, 0.9%.
about 70 percent of the atmosphere is nitrogen
The maximum percentage of nitrogen by mass is about 78.08%, which is the composition of nitrogen gas (N2) in the atmosphere.
Around 2.7% of Martian atmosphere is nitrogen.

Approximately 78% of Earth's atmosphere is composed of nitrogen gas.
The Earth's atmosphere contains 78% nitrogen.
About 79% of earth's atmosphere is Nitrogen.
78% of the atmosphere is nitrogen
As far a i remember 78%
The process that has changed the percentage of nitrogen in the Earth's atmosphere is biological nitrogen fixation, where certain bacteria convert nitrogen gas into a form that plants can use. This has led to an increase in nitrogen levels over time.
