Verified step by step guidance

1. Begin by understanding the classification of matter. Matter is anything that has mass and takes up space. It can be classified into different categories based on its composition and properties.
2. Recognize that 'substance' refers to a form of matter that has a uniform and definite composition. Substances can be either elements or compounds.
3. Identify that an 'element' is a pure substance that cannot be broken down into simpler substances by chemical means. Elements are the basic building blocks of matter.
4. Understand that a 'mixture' is a combination of two or more substances where each substance retains its own chemical identity. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
5. Conclude that 'matter' is the broadest term that encompasses all other terms: elements, substances, and mixtures. It is the overarching category under which all forms of matter are classified.
