the particles that makes up an atom are
protons
neurons
electrons
among which electrons are the smallest.
The particles in the nucleus of an atom are the protonsand the neutrons. We call particles that make up the atomic nucleus nucleons, and this word is just a way to say "the particles that make up an atom's nucleus" in an abbreviated manner.
Sub-atomic particles are even smaller particles that make make an atom
Dalton discovered the particles that make the atom and the atom itself
These particles are: neutron, proton, electron.
Neucleus, Proton and electrons
An Atom. It's the world's smallest particles of matter, atom's is known to be 20 times smaller than an average coffee bean.

The three subatomic particles that make up an atom are the protons, neutrons, and electrons. The protons are positively charged particles that are located in the atomic nucleus at the center of the atom. The neutrons are particles that have no charge and are also located in the nucleus. The electrons are negatively charged particles that are located in the electron cloud surrounding the nucleus.
The electron is the lightest of the three particles that make up an atom, with a mass of approximately 9.11 x 10^-31 kilograms.
There're two particles in the atom nucleus (protons and neutrons)
