9 Flavours
In particle physics, a characteristic used to differentiate the types of leptons and quarks. Leptons (electron, neutrino) have 3 flavours (associated with the electron, the muon, and the tau), and quarks have 6 flavours (up, down, strange, charm, bottom, top). flavours are used to distinguish particles that only differ by their masses, while their other properties (electric charge, etc.) are similar.
