Verified step by step guidance

Understand the classification of matter: Matter can be classified into elements, compounds, and mixtures. Elements consist of only one type of atom, compounds consist of two or more different atoms chemically bonded, and mixtures are physical combinations of substances.
Recall the definition of an atom: An atom is the smallest unit of an element that retains the properties of that element, but it does not represent a compound.
Recall the definition of a molecule: A molecule is the smallest unit of a compound that retains the compound's chemical properties. It consists of two or more atoms chemically bonded together.
Differentiate between a molecule and a mixture: A mixture is a physical blend of substances where each substance retains its own properties, so it is not the smallest unit of a compound.
Conclude that the smallest unit of a compound that retains its chemical properties is a molecule.
