Either an atom or a molecule, depending on the substance.
An atom is the smallest particle of a substance.

Molecule
It is a molecule of the substance.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.

Either an atom or a molecule, depending on the substance.
The smallest particle of a substance that still retains all the chemical properties of that substance is called a molecule. In the case of elements, the smallest particle is an atom, which retains the unique properties of that element. Molecules are made up of atoms bonded together in specific arrangements that determine the chemical behavior of the substance. Therefore, the smallest particle of a substance that is still that substance does indeed possess all the properties of that substance.
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is called a molecule. Each molecule is made up of one or more atoms chemically bonded together.
