Quarks are fundamental particles. They are the building blocks for hadrons.

  • To make protons and neutrons, you only need two types of quark: the up quark (u) and the down quark (d).
  • Another quark called the strange quark (s) allows you to make more particles witha property called strageness.
  • Antiparticles of hadrons are made from antiquarks.

Quarks and their properties

Antiquarks and their properties

  • Baryons are made from 3 quarks.
  • Evidence for quarks came from hitting protons with high energy electrons.
  • The way the electrons scattered showed there were three concerntrations of charge (quarks) inside the proton.
