Structure of the Atom: Understanding Subatomic Particles A Comparison of Three Subatomic Particles The proton, the neutron, and the electron are the three so-called subatomic particles The proton and neutron are each approximately 1000 times more massive than the electron And both are located in the nucleus This means that nearly all the mass of an atom is located in its very dense center
