Verified step by step guidance

Begin by understanding the classification of matter. Matter is anything that has mass and takes up space. It is the broadest category in the classification of matter.

Matter can be divided into two main categories: pure substances and mixtures. Pure substances include elements and compounds, while mixtures are combinations of two or more substances.

Elements are substances that consist of only one type of atom and cannot be broken down into simpler substances by chemical means.

Compounds are substances formed when two or more elements are chemically bonded together in fixed proportions.

Mixtures are combinations of two or more substances where each substance retains its own chemical identity and properties. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
