In particle physics, different generations describe different groups of particles that have closely related properties. For example, there are three different generations of quarks , each one containing two quarks. In the first generation, you'll find the d and u quarks, in the second s and c and in the third b and t. The higher the generation the heavier the particle.	Quarks Generation Symbol Flavor Electric Charge 1st d down -1/3 u up 2/3 2nd s strange -1/3 c charm 2/3 3rd b bottom -1/3 t top 2/3
In every generation there are also two leptons .	Leptons Generation Symbol Flavor Electric Charge 1st e electron -1 νe electron neutrino 0 2nd μ muon -1 νμ muon neutrino 0 3rd τ tau -1 ντ tau neutrino 0
