Yet another definition of a pure substance suggests that any material made of the same kind of atoms is a pure substance. So individual elements in the periodic table and stuff made "purely" of them are pure substances. Other stuff is just homogeneous or heterogeneous mixtures.
Learn how to distinguish pure substances or compounds with mixtures, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
Pure substances are made up of a single element, or a single compound. Table salt is a pure substance because it is made up of only the compound NaCl (sodium chloride).
Sodium chlorate is a pure substance with a chemical formula NaClO3. It is distinct from a mixture of sodium chloride (NaCl) and oxygen (O2).
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
