Oxygen
Nitrogen.
The element that makes up approximately 0.9 percent of the air is argon. Argon is a noble gas and is the third most abundant gas in the Earth's atmosphere, following nitrogen and oxygen. It plays a minimal role in chemical reactions due to its inert nature.
The element that makes up about 70 percent of the air you breathe is nitrogen. Nitrogen constitutes approximately 78 percent of Earth's atmosphere, making it the most abundant gas. The remaining components include oxygen, argon, carbon dioxide, and trace gases. Oxygen, while essential for human respiration, only accounts for about 21 percent of the atmosphere.
Seventy-eight percent of air is composed of nitrogen. Nitrogen is a colorless, odorless gas that plays a crucial role in the Earth's atmosphere. It is relatively inert, which means it doesn't easily react with other substances, making it a stable component of the air we breathe. Oxygen, which makes up about 21% of air, is the second most abundant gas.
