This category is primarily divided into elements and compounds. A pure substance represents a single form of matter with a fixed and uniform composition, whereas a mixture consists of two or more substances physically combined, with each component retaining its own chemical properties.

Filtration is effective for separating solids from liquids, while distillation leverages differences in boiling points to separate liquids. Chemists rely on this classification to predict reactions and design experiments.
For instance, table salt is a compound made from sodium and chlorine, and the resulting crystal structure has a completely different taste and function compared to its individual components. Compounds, on the other hand, are created through chemical reactions where atoms are shared or transferred.

The components in a mixture maintain their original properties and can be present in varying proportions. Feature Pure Substance Mixture Composition Fixed and uniform Variable Chemical Bonding Components are chemically bonded Components are physically mixed Separation Requires chemical changes Can be separated by physical means.
