| − | A hadron is a particle that is composed of [[quark]]s. Based on the number of quarks it is made up of, there are two types of hadrons. [[Baryon]] is a kind of hadron that is made up of three quarks. Well known baryons are the nucleons—[[proton]]s and [[neutron]]s. A [[meson]] is the second type of hadron that is composed of one quark and one antiquark. A [[pion|pi meson]] is an example of meson. In a hadron, the quarks are held up together by the [[strong interaction]], which is mediated by the exchange of [[ | + | A hadron is a particle that is composed of [[quark]]s.

Baryons like protons and neutrons are held together inside the [[atomic nucleus]] by the [[nuclear force]], which is a residual force that arises from the strong interaction. Inside the nucleus, this residual force is mediated by the exchange of pi mesons. | Baryons like protons and neutrons are held together inside the [[atomic nucleus]] by the [[nuclear force]], which is a residual force that arises from the strong interaction.
