Nitrogen and Oxygen
Actually if you're referring to the air we breathe then oxygen isn't the most abundant, our air is roughly 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.
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 common gas in the air we breathe is nitrogen, making up about 78% of Earth's atmosphere. Oxygen is the second most abundant gas, comprising about 21% of the air. Both gases are essential for supporting life on Earth.
Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
78% of the air that we breathe is nitrogen gas.
Air is rich in nitrogen, oxygen, and other gases such as argon, carbon dioxide, and water vapor. Oxygen is the most abundant element in the Earth's atmosphere, making up about 21% of the air we breathe.
The most abundant gas in Earth's atmosphere is nitrogen, which makes up about 78% of the air we breathe. Oxygen is the second most abundant gas in the atmosphere, accounting for around 21% of its composition. Other gases like argon, carbon dioxide, and trace gases are also present in smaller amounts.
The most abundant elements in air are nitrogen, oxygen, and argon. The gases typically excluded from this list are carbon dioxide, helium, and neon.
No. Air is a mixture of gases. The most abundant are nitrogen (78%) and oxygen (21%). Refer to the related link for a listing of the ten most abundant gases in the atmosphere.
Nitrogen and oxygen are the two most abundant gases in the air. They are actually elements and not compounds. The two most abundant compounds would be water vapor and carbon dioxide.
The most abundant element in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant element in the air, at around 21%.
