As a small participation exercise I invite you to do the trivial corresponding calculus. To ease them remember that the energy of the electronic shell of the H atom is 13.6 eV and that its Bohr radius measures 0.53* 10^-10 m. Do not forget to take into account the fact that the angular momentum of its electronic orbital is integer while the electron and proton spin is half integer. In the previous treatment of the Q charge of these two particles it has not been necessary to take into account the spin since they both have the same one.
Well, as you have found the H atom Q charge has the same value. Considering that the muon has also the same one (it can be directly deduced from load XIV and XVI) we have thus identified a quadruplet of physical bodies which obey to the same Q charge quantization.
