- Oxygen (O2): About 21% of air is oxygen gas, which is essential for breathing.
- Other Gases: Air also contains small amounts of other gases like carbon dioxide, neon, and hydrogen.
| Gas | Percentage |
|---|---|
| Nitrogen (N2) | 78% |
| Oxygen (O2) | 21% |
| Other Gases | 1% |
Why Air Is Considered a Gas
Air is considered a gas because it possesses the characteristics of a gas:
