A neutron has a charge of zero, meaning it is electrically neutral.
This neutrality is a fundamental characteristic of neutrons, which are one of the three main subatomic particles found in an atom, alongside protons and electrons. Protons carry a positive charge, while electrons carry a negative charge. Neutrons, however, do not carry any charge, which allows them to contribute to the mass of an atom without affecting its overall electrical charge. This property is crucial for the stability of atomic nuclei, as neutrons help to balance the repulsive forces between the positively charged protons.
