What is the atomic structure?

The atom starts with the electron which moves around the outside of the atom. The the nucleus at the center of the atom. The nucleus is made up of two particles or nucleons, since they are found in nucleus. Those particles are the proton and neutron. But even these can be broken down to particles called quarks which are held together with gluons. The atom starts with the electron which moves around the outside of the atom.
