Explanation:

1. An atom is the single piece of any pure element and building - block for all substances.
2. A molecule is two or more atoms chemically - bonded together.
3. Atoms, molecules, and ions are the smallest units of a substance with the same chemical formula.
4. Matter has mass and takes up space.
5. Pure substances can be elements (made of one kind of atom) or compounds (made of two or more elements chemically combined).
6. Mixtures are made of 2 or more different types of particles. Heterogeneous mixtures have non - uniform composition, and homogeneous mixtures have uniform composition at the particle level.
