The particle that has no charge and is located in the nucleus of an atom is called a neutron. Neutrons are one of the three primary subatomic particles, along with protons and electrons. While protons carry a positive charge and electrons carry a negative charge, neutrons are neutral, which means they do not have any electric charge at all.
Neutrons play a crucial role in the stability of an atomic nucleus. They help to offset the repulsive forces that occur between the positively charged protons. If an atomic nucleus had only protons, the protons would repel each other due to their like charges, making the nucleus unstable. Neutrons provide an attractive force through the strong nuclear force, allowing nucleons (protons and neutrons) to stay bound together within the nucleus.
