| Strong interactions bind quarks together such that they form neutrons or protons. Additionally, they are also responsible for binding neutrons and protons to atomic nuclei together. | Strong interactions bind quarks together such that they form neutrons or protons.

| Gluons couple to all particles that carry the charge of quantum chromodynamics, which is known as color charge. In other words, only particles with color charge (quarks and gluons) take part in strong interactions. This is again analogous to electromagnetic interactions since only particles that carry electric charge take part in electromagnetic interactions, i.e. couple to photons. | Gluons couple to all particles that carry the charge of quantum chromodynamics, which is known as color charge.
