Any tangible object made of matter is called a substance. Substance can either be pure or impure.
Elements and compounds come under the category of pure form of substance as they are formed from a single type of atoms or molecules evently distributed throughout.
Mixtures (homogeneous and heterogeneous) are examples of impure substance as they contain more than one type of atoms or molecules.
