Kingston Kim · Answer 1

The majority of the air we breathe is made up of nitrogen and oxygen, though you'll also find argon, carbon dioxide and other gases in trace amounts.

Jester · Answer 2

It is made up of about 78% nitrogen, 21% oxygen, and many other elements like argon, water vapor, and other things. The most common element of air is nitrogen, and it is considered a mixture because we can distinguish between the elements in the air we breath, and we can physically separate the elements in the air.
