Atom structure

  1. Oct 17, 2012 #1
    Just one quick question I couldn't find an answer on the internet to, after a long search.
    We are taught that atoms are made from protons, neutrons and electrons only. There are many other leptons and hadrons existing, but where are they in this story?

    Okay, so in a usual atom, only protons, electrons and neutrons exist. But how are those exotics produced?

    You smack "normal" particles together with high energies at places like CERN and Fermilab. Some of the energy creates the masses of the "new" particles.
