Which type of particle has a positive charge?

In the realm of atomic structure, protons are the particles that carry a positive charge. They are found in the nucleus of an atom, alongside neutrons, which have no charge, and they are vital in determining the overall charge and identity of an atom. The positive charge of protons plays a crucial role in the electromagnetic force, which attracts negatively charged particles, like electrons, and helps to maintain atomic structure.

While neutrons are neutral and do not carry any charge, photons are elementary particles of light and also do not have a charge. Electrons, on the other hand, are negatively charged particles. Therefore, in the context of charged particles, protons are uniquely identified by their positive charge, making them essential for both the structure of atoms and the interactions that occur within and between them.
