A molecule of the substance.
An atom of an element may exhibit different characteristics when it is bound to other atoms of the same element.
Examples are common oxygen (O2) and ozone (O3) with altered chemical properties.
Or carbon as graphite (hexagonal lattice) and diamond (tetrahedral lattice), which demonstrate very different physical properties.
If it an element, then the smallest unit that keeps all the physical and chemical properties is an atom.
It it is a compound, then the smallest unit that keeps all the physical and chemical properties is a molecule or unit formula.
The molecule of the substance. If the substance is pure, like pure gold, then the smallest particle is the atom. There are smaller parts that make up the atom , but they do not carry characteristics specific to the substance.
The smallest unit of a substance that behaves as that substance would be considered a molecule.
A molecule of the substance, or, if the substance is an element, then an atom.
This is the old definition of a molecule. However in modern usage, the term molecule is reserved for a covalently bound particle.

an amorphasolid
The wave diffracts and behaves like the opening is a point source.
A substance can be categorized into several categories. If a substance cannot be separated through physical means (e.g., distillation, magnetism) it is a pure substance. If a substance can be separated through physical means, it is a mixture. If a mixture is uniform throughout, it is a homogenous mixture, like saltwater. If it is not (i.e., there are different parts to it, like a can of soda), it is a heterogeneous mixture. If a pure substance can be separated through chemical means, it is a compound, like glucose, which is made of carbon, oxygen, and hydrogen. If a substance cannot be separated by chemical means, it is an element, like oxygen, which is made of just oxygen. A substance can be in multiple categories.

An oxygen atom
This property is the surface tension.
An alkaline substance like milk, Maalox or simlliar ingredients.

it behaves like a line
Alpha emission is a 4helium nucleus, which behaves like a particle. Beta emission is an electron, which behaves like a particle. Gamma emission is a photon, which behaves like a particle. Experiments can also be set up to show their wavelike properties (for alpha, beta, and gamma radiation).
