subatomic particle
The atom is the smallest known particle.
This particle is the atom.
The smallest part of all matter has been identified to be a "quark."
An atom is the smallest building block of matter that retains the characteristics of that matter.
The smallest particle of matter still retaining the elemental properties of matter is an atom. Atoms have building blocks, and they are protons, electrons and neutrons. But the atom, because it is made of these elemental building blocks, is the furthest we can break matter down and retain the elemental structure.We can further break down the building blocks of matter, the particles that make up the atom, but the resultant particles are not stable. They spontaneously go through changes and disappear.It is not an atom it is a quark
A quark is the smallest particle in matter.

The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
