* The electron-like leptons (i.e. not the neutrinos), the W<sup>±</sup> bosons, and all quarks carry an intrinsic electric charge.

* In a normal environment, electrons and protons carry a charge, equal in magnitude and opposite in sign, neutrons do not carry a charge, and everything else that might carry a charge (muons, taus, some mesons, heavy quarks, W bosons) is vanishingly rare (and decaying very soon).

* In a normal environment, electrons and protons carry a charge, equal in magnitude and opposite in sign, neutrons do not carry a charge, and everything else that might carry a charge (muons, taus, electron-like antileptons, some mesons, heavy quarks, W bosons) is vanishingly rare (and decaying very soon).

** Photons do not carry a charge, but they do carry energy, and are the mediators of the electromagnetic interaction.

* At the atomic scale, one need deal with quantization of angular momentum, and solve for lowest energies with the Schrödinger equation, and the electromagnetic interaction is described by QED, and the Heisenberg principle applies. Suffice to know that electrons do not slam into the nucleus, despite the fact that at larger scales:
