I believe that would be the electron.

Not quite. Electrons are made of quarks, which are smaller than electrons allong with muons, gloums, leptoms, femioms, tracheons, among others.
The atom is the smallest known particle.
yes this is called an atum a atum is a the smallest thing known to man some people say this is not true but it is there is no such thing as atum's butt it is a living particle on an animal or living breathing oganism thank you Alyce D
The smallest particle of an element is called an atom.
An atom is the smallest particle of a substance.
observable ? i'd say quarks.
A quark is the smallest particle in matter.
you can't get mass you can acquire it mass is govern by a particle known as the Bassa Nova Higgs the smallest particle in the mutiverse or universe.
The smallest particle in the atom is the electron.
A quark is the smallest known particle, which makes up protons and neutrons found in the nucleus of atoms. This means that quarks are smaller than protons, neutrons, atoms, and molecules.
The smallest particle in quantum physics is typically considered to be the quanta of energy known as a photon, which is a fundamental particle that carries electromagnetic radiation. However, there are also other elementary particles such as electrons, quarks, and neutrinos that are considered fundamental building blocks of matter.
An atom is a particle, the smallest particle that can exist by itself.
A Higgs-Boson particle.
