Understand that quarks are fundamental particles, and that quarks come in six flavours (types): up, down, strange, charm, top and bottom.
Taught in: Quarks: six flavours · 5 questions
Recall and use the charge of each quark flavour, and understand that each antiquark has the opposite charge to its quark.
No other properties of quarks are required.
Taught in: Quark charges and antiquarks · 5 questions
Recall that protons and neutrons are not fundamental particles, and describe their quark composition.
Taught in: What protons and neutrons are made of · 5 questions
Understand that a hadron is either a baryon (three quarks) or a meson (one quark and one antiquark).
Taught in: Hadrons: baryons and mesons · 5 questions
Describe how quark composition changes in β⁻ decay and in β⁺ decay.
Taught in: Beta-minus decay: a down quark becomes an up quark, Beta-plus decay: an up quark becomes a down quark · 10 questions
Recall that electrons and neutrinos are fundamental particles known as leptons.
