Based on the composition of dry air in the Earth's atmosphere, the gases can be organized from Greatest percentage composition to Least percentage composition as follows:

  1. Nitrogen (N2)
  2. Oxygen (O2)
  3. Carbon Dioxide (CO2)
  4. Other Gases

This order reflects the typical abundance of these gases in the atmosphere, with nitrogen being the most prevalent, followed by oxygen, then carbon dioxide, and finally other trace gases that make up the remaining portion of the atmosphere.
