A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3).
