Nitrogen
Nitrogen is the most abundant gas in the air. It makes up 78% of the air in the atmosphere.
Nitrogen gas makes up most of the atmosphere. However carbon dioxide extinguishes a burning splint and is found in a small amount in the atmosphere Nitrogen gas. It is an inert gas that makes up over 70% of the Earth's atmosphere.
Nitrogen, at about 80%.
Nitrogen, N2, (about 79% in air) is a rather inert gas.
Oxygen
It's a noble gas; it doesn't react with much of anything.
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.
The most abundant gas in the air we breathe is nitrogen, which makes up about 78% of Earth's atmosphere. Oxygen is the second most abundant gas, making up about 21%.
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%. The inert gas argon (Ar) is the third most abundant gas at 0.93%.
It is oxygen.
