A proton is a subatomic particle, symbol p or p+ , with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron. Protons ...

en.wikipedia.org/wiki/Charged_particle

In physics, a charged particle is a particle with an electric charge. It may be an ion , such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can be the electrons and protons themselves, as well as other elementary particles, like positrons.
