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

The particle that has no charge and is found in the nucleus is the neutron. Neutrons are one of the three primary subatomic particles that make up an atom, with the other two being protons (which are positively charged) and electrons (which are negatively charged). Neutrons play a crucial role in the stability of the nucleus, as they help to bind protons together despite the repulsive forces that arise due to the positive charges of the protons. The presence of neutrons also influences the mass of an atom, as they contribute to the overall atomic weight without adding an electrical charge, thus maintaining the atom's neutrality if balanced with the number of protons. This unique property makes neutrons essential for the structure of atomic nuclei in all elements.
