[[File:Nucleus drawing.svg|thumb|right|A model of the atomic nucleus showing it as a compact bundle of the two types of nucleons: [[Proton]]s (red) and [[neutron]]s (blue). In this picture, the protons and neutrons look like little balls stuck together, but an actual nucleus (as understood by modern [[nuclear physics]]) does not look like this. An actual nucleus can only be accurately described using [[quantum mechanics]]. For example, in a real nucleus, each nucleon is in multiple locations at once, spread throughout the nucleus.]]
