A proton is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron
an elementary particle that is a quantum of the electromagnetic field and this one quantum of electromagnetic energy is called a photon, it is the minute energy packet of electromagnetic radiation and it always move at the speed of light in vacuum, 299792458 m/s. By studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years. At the dawn of the 20th century, Max Planck and Albert Einstein turned physics on its ear by introducing the notion of quanta. Einstein's paper of 1905 dealt with the particle nature of light, but didn't call the particles photons.
note :The term quantum is the smallest elemental unit of a quantity, or the smallest discrete amount of something or it means the smallest particles
