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 abundant gas in Earth's atmosphere, making up about 21% of the air we breathe.

Oxygen is the 2nd most common gas in air.Air composition (in % by volume and by moles):79% Nitrogen20% Oxygen1% other gases (argon, carbon dioxide, water vapor etc.)
oxygen --- I started to leave this because it is the wrong answer.
Oxygen, which is about 21% while nitrogen is the most abundant at 78%.
