A helium atom contains two protons, two neutrons, and two electrons, and it is electrically neutral. Each proton contains two up quarks and one down quark, and each neutron contains two down quarks and one up quark. Electrons have a charge of -e, up quarks have a charge of +2e/3, and down quarks have a charge of -1e/3.

The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. You perform a nuclear physics experiment in which you bombard nitrogen-14 nuclei with very high speed carbon-12 nuclei emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely and a mix of different particles are emitted, including electrons, protons,...
