Detailed explanation-1: -The composition of gases in the atmosphere are: nitrogen is about 78% and oxygen is 21% and the remaining 1% mostly has argon, carbon dioxide and other gases like hydrogen, helium, neon, krypton, xenon, methane, ozone and water vapour. Apart from these gases, tiny dust particles are also present in our atmosphere.

Detailed explanation-2: -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 other gases, too, such as carbon dioxide, neon, and hydrogen.

Detailed explanation-3: -Gases. The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%.

Detailed explanation-4: -Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

Detailed explanation-5: -The composition of air by volume is: Nitrogen-78%, oxygen-21% and other gases such as carbon dioxide, argon, methane, ozone and water vapour are present in small quantities.
