It would be an atom or a molecule (made up of more than one atoms)
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.
Element
The smallest particle of a substance that retains all properties is an atom. An atom is composed of a nucleus containing protons and neutrons, surrounded by electrons. In some cases, atoms can combine to form molecules, but the individual atom remains the smallest unit that retains the substance's properties.

Yes, the smallest particle of a substance, such as an atom or molecule, retains all the properties of that substance. These properties include chemical makeup, physical characteristics, and behavior in reactions or interactions with other substances.
The smallest particle of a compound that can exist and still retain the characteristic properties of that substance is a molecule. For gaseous elements, individual atoms are the smallest particle that retains the characteristic properties of the element.
A molecule; the definition is: The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
