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%.omposition of the Atmosphere extended definition. The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The most abundant gas in the atmosphere is nitrogen, with oxygen second.
The most abundant gases in the atmosphere are nitrogen at 78 percent and oxygen at 21 percent, while the trace gases methane, neon and helium make up around one-tenth of 1 percent of the atmosphere. Oxygen, nitrogen and argon are classified as permanent gases because their percentages always remain the same.
