A quark is a particle which is only ever found inside other particles. No solitary quark has ever been found, but there are good theoretical reasons for believing that they exist. There are 6 types of quark: the up, down, top, bottom, strange and charm quark. They carry an electric charge which is a fraction of that carried by the electron. They have mass, the different types having different masses, and they also carry a type of charge called "color".
Quarks combine with each other to produce other particles which we can detect. Up and down quarks group together in threes to produce protons and neutrons. A quark combines with an anti-quark to produce a meson |
