Which subatomic particle is considered to have a positive charge?

The proton is the subatomic particle that carries a positive charge. In the context of atomic structure, protons are found within the nucleus of an atom, alongside neutrons, which are neutral and do not have a charge. Electrons, on the other hand, are negatively charged particles that orbit the nucleus. Photons are particles of light and do not possess any charge at all. The presence of protons in the nucleus, with their positive charge, plays a crucial role in determining the overall charge of an atom and significantly influences how it interacts with other atoms. The balance of protons and electrons defines an atom's electroneutrality or ionization, making the understanding of protons fundamental in chemistry and physics.
