Which type of particle is found in the atomic nucleus and has no charge?

The type of particle found in the atomic nucleus that has no charge is a neutron. Neutrons are subatomic particles that, along with protons, make up the nucleus of an atom. While protons have a positive charge, neutrons are neutral, which means they do not possess an electric charge. This neutrality plays a crucial role in the stability of the atomic nucleus, as neutrons help to mitigate the repulsive forces between positively charged protons in the nucleus.

Protons, although also found in the nucleus, carry a positive charge. Electrons, on the other hand, are negatively charged particles that orbit the nucleus and are not found inside it. Ions are atoms that have gained or lost one or more electrons, resulting in a net electric charge, but they also do not refer to any specific types of particles within the nucleus. Therefore, the neutrons' unique property of being electrically neutral makes them essential components of atomic structure and stability.
