The correct answer is: 0

The charge of a neutron is indeed neutral, meaning it has no charge at all, which is represented by zero. Neutrons are subatomic particles found in the nucleus of an atom, alongside protons. While protons carry a positive charge and electrons carry a negative charge, neutrons do not have any electric charge. This neutrality plays a crucial role in balancing the positive charge of protons within the nucleus, helping to maintain atomic stability. The presence of neutrons allows atoms to exist in different isotopes, which vary in their number of neutrons but retain the same chemical properties because the number of protons (and thus the atomic number) remains unchanged.
