This question already has an answer here:

Just like, in a Bohr model, the atom has a particular structure, what is it like inside of a nucleon? Like, are there particular ways the quarks are arranged, and what about the binding energy that comprises the majority of the mass of the nucleon?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ Hi I hope you get a better picture in the answers but to address your first question, my basic personal picture is: Each nucleon has 3 quarks, called valance quarks. The force between these quarks is carried by gluons and in addition there are virtual quark-antiquark pairs continually being created and then decaying. The neutron has 2 down and one up quark and the proton has 2 up and one down quark. I am open to correction on this so hopefully you will get an answer we both can learn from...regards $\endgroup$ – user74893 Apr 7 '15 at 20:15

  • $\begingroup$ As a tagging matter, nucleon structure spans the boundary of nuclear and particle physics and makes only the most modest of contribution to atomic physics. $\endgroup$ – dmckee Apr 7 '15 at 20:19

    $\begingroup$ The question that @Mobin suggests is clearly not a duplicate. This question concerns the distribution and behavior of partons within a single nucleon, not of nucleons within a nucleus. $\endgroup$ – dmckee Apr 7 '15 at 22:32
