When the content of the matter is considered, there are elements, compounds and mixtures.
If the shapes are concerned, there are crystalline and amorphous matter.
Matter have pigments in its composition, then the color will be showed when light get to the matter.
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.

The main classification criterion is the chemical composition. Minerals are classified as oxides, sulfides, halides, sulfates, silicates, or carbonates. Some elements are also classified as minerals. There's also a metallic and non-metallic mineral classification.

A chemical change involve a change of composition.

Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
Chemistry is the name of the science which studies composition, matter and structure.Specifically, the science in question deals with matter - elements which have mass and weight - and substances. It emphasizes the composition and properties of matter and substance. It also examines structure.
