The proton-neutron model of the nucleus, proposed by physicists such as Ernest Rutherford and later developed by others, describes the atomic nucleus as being composed of protons and neutrons, collectively known as nucleons. Protons carry a positive charge, while neutrons are electrically neutral. This model explains the stability of the nucleus, as the strong nuclear force binds these nucleons together, overcoming the repulsive forces between protons due to their like charges. The balance of protons and neutrons determines the properties of the element, including its atomic number and mass.
