This smallest "thing" is the atom.
The smallest unit of a pure substance that still has the chemical properties of that substance is called an atom. Atoms can be further broken down into subatomic particles such as protons, neutrons, and electrons.
If that substance is an element, the smallest part is the atom which, if broken down further into atomic particles, loses its identity.
Chalk can be broken into pieces.
Elements can be broken down into smaller pieces: a compounds smallest particle is a molecule
To break into small pieces is to pulverize. If the substance is broken down far enough it will become powdered.

No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.

The smallest substance that can exist on its own is an atom. Atoms are the basic building blocks of matter and cannot be further broken down into smaller particles without losing their chemical properties.
The root "mole" refers to heaviness or weight; these are pieces of matter. The suffix "cules" refers to the very small size of molecules; these are the smallest pieces of a given substance that retain the chemical characteristics of that substance.
An atom is the smallest particle of a substance.
An atom is the smallest particle of a substance.
Molecules are the smallest part of a substance. Molecules have all the properties of a substance.
