* Solid: Minerals are naturally occurring solid substances. Air is a gas, which means it lacks a fixed shape and volume.
* Inorganic: Minerals are inorganic compounds, meaning they are not formed from living organisms. While air contains some organic compounds like pollen and dust, its main components (nitrogen, oxygen, etc.) are inorganic.
* Naturally Occurring: Minerals are found in nature. Air is a mixture of gases, but it isn't formed by a natural process like crystallization.
* Specific Chemical Composition: Minerals have a defined chemical formula. Air is a mixture of gases with varying proportions.
* Ordered Internal Structure: Minerals have a crystalline structure, meaning their atoms are arranged in a specific, repeating pattern. Air lacks such a structure.
In summary, air is a mixture of gases, not a solid, inorganic, naturally occurring substance with a specific chemical composition and ordered internal structure. These are the defining characteristics of a mineral, which air does not possess.
