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.
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.
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, Oxygen, Carbon- dioxide, dust, vapours, etc. Nitrogen is the most abundant.
We breathe in all gases present in the air. The two most abundant constituents of air are nitrogen and oxygen.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
