Q's about Electrons, protons, and neutrons

  1. Jul 11, 2005 #1
    This might be a dumb question, but in all my years of chemistry and physics studies I have never gotten an explanation of where electrons and protons get their charges from. I don't know if this is the right forum, maybe one of the physics forums might be better? Maybe a physical chemist can answer this question? why do protons and electrons have +/-1.6x10^-19 C of charge and neutrons have 0 charge?

    The inner quark structure of the 2 baryons is of such nature that the charges add to +1e for proton and 0 for neutron. The electron has the charge -1e and is a fundamental particle.

    You'll have to understand that experiments gave those results and from then on it was up to the theoretical physicists to come up with the best model to account for those experimental results. The SM is the best model so far for elementary particles & interactions.

    Moving this to Particles ....

    Gravenewworld : a physical chemist can not answer this question. It belongs in the realm of Nuclear/Particle Physics.
