what is the percentage of nitrogen in the atmosphere?

It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.

So we measure the percentage of gases in dry air - air that has had all the Water vapour removed by cooling it until it condenses. You should know that 21% is Oxygen (O2), 78% is Nitrogen (N2) and that most of the remaining gas (0.9%) is the Noble Gas, Argon.

By volume, the dry air in Earth's atmosphere is about 78.09 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other 0.03 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.

The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere.

The atmospheric gases include nitrogen, oxygen, carbon dioxide, water vapor, argon, and trace gases. Among the trace gases which are present in only small amounts, are neon, helium, krypton, and xenon. Nitrogen is the most abundant gas in the atmosphere. Nitrogen makes up 78 % of the Earth's atmosphere.

The atmosphere is like a blanket around the Earth -- and is made up of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide and trace amounts of other gasses. One of these gasses is water vapor, which is its most variable component.

Earth's atmosphere. Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.

The atmosphere is composed of a mix of several different gases in differing amounts. The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%.

Nitrogen. Nitrogen is present in the atmosphere mainly as the dimeric molecule N2. See below for a summary of information on atomic nitrogen. There are two primary isotopes of atomic nitrogen with a ratio of 14N/ 15N = 272.

The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

The principal components of the atmosphere, nitrogen (78.08 percent), oxygen (20.95 percent), argon (0.93 percent), and carbon dioxide (0.038 percent), occur in seawater in variable proportions, depending on their solubilities and oceanic chemical reactions.

The atmosphere looks like a blanket of gas when you look at it from space or the ground. ... Overall, the atmosphere is made up of a few main molecules. The air above you is made of 78% nitrogen (N2), 21% oxygen (O2), 0.9% argon (Ar) and 0.04% carbon dioxide (CO2). That's it.
