Answer:

Explanation:

An element is a substance that cannot be broken down by an ordinary physical process. An element is made up of atoms having the same atomic number. There is a periodic table of elements that has all the elements arranged according to there atomic number.

Air is not an element because it actually contains atoms of more than one element (including oxygen, nitrogen and noble gases). Air also contains compounds such as CO₂. These substances that air contains are physically combined, hence air is a mixture.
