Air is primarily composed of nitrogen and oxygen, with small amounts of several other gases. Here's a breakdown:

1. Nitrogen (N2) - about 78%
2. Oxygen (O2) - about 21%
3. Argon (Ar) - about 0.93%
4. Carbon Dioxide (CO2) - about 0.04%
5. Neon, Helium, Methane, Krypton, Hydrogen, and Xenon are also present in trace amounts, each comprising less than 0.01% of the atmosphere.
6. Water vapor (H2O) is also a variable component of air, ranging from less than 0.01% to 2%.

It's important to note that these percentages can vary slightly depending on the location and the weather.
