Deep Inside the Atom

These questions cover the Standard Model skills that school trial papers test again and again: quark make-up and charges, leptons and bosons, antimatter and annihilation, conservation rules, and how accelerators work and test the model. Use $c=3.00\times 10^8$ m/s, $q_e=1.602\times 10^{-19}$ C and $m_p=1.673\times 10^{-27}$ kg. They start easy and get harder. Stuck? Tap Show a hint for one step at a time.
