Is Air an Element Compound or Mixture? [ANSWERED]

Air is a matter that consists of various elements and compounds such as Nitrogen (about 78 ) Oxygen (about 21 ) Argon (1 ) and little amount of other matter 

Dry air in our atmosphere consists primarily of nitrogen. (about 78%), oxygen (about 21%) and argon (0.9%). As students will learn over the course of the 

  • Is air a compound or element?

    Air is a mixture and not a compound because of the following reasons: Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air. Air shows the properties of all the gases present in it.

  • Is air an element or gas?

    Air is nothing but a mixture of a variety of gasses. The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.).

  • Is air a pure element?

    - Air is not supposed to be considered as a pure substance. Because air is a mixture of different gases. - Air mostly contains nitrogen and oxygen in about 78% and 20% respectively. Note: Elements and compounds have a constant composition throughout and can thus be said as pure substances.
  • Air is not an element. It is made up of different gases like hydrogen, carbon dioxide and oxygen mixed together. Hence air is a mixture.
