Is pure air an element or a compound?

Answer 1

If you are talking about the gas we breath in the air, it's a compound. Pure oxygen as a gas exists as a molecule. Oxygen as an element, is unstable and as far as I know doesn't exist as a single element in nature. It will always occur in combination with something else, such as H2O or O2.

Answer 2

Pure air is a mixture of gases, primarily nitrogen and oxygen, along with smaller amounts of other gases such as carbon dioxide and argon. It is not considered a pure element or compound because it is made up of multiple different substances.

Answer 3

Air is always a mixture and neither an element nor a compound. As usual with mixtures, the concept of purity does not apply to air.

Answer 4

Air is a mixture.
