What type of particles are located in the nucleus and carry a positive charge?

The particles located in the nucleus that carry a positive charge are protons. In the atomic structure, the nucleus is composed of protons and neutrons, which together make up most of the atom’s mass. Protons are fundamental particles that define the identity of an element; for instance, an atom with six protons is identified as carbon. The positive charge of protons plays a crucial role in the electromagnetic forces that bind electrons around the nucleus, creating a stable atom.

Neutrons, while also found in the nucleus, do not carry any charge; they are neutral. Electrons, on the other hand, are negatively charged particles that orbit the nucleus. Positrons are the antimatter counterparts of electrons and do not exist in the nucleus of ordinary matter. Thus, the correct answer identifies protons as the positively charged particles within the nucleus.
