Which of the following statements about neutrons is correct?
Neutrons have no charge and are found in the nucleus of an atom
An atom is built from three sub-atomic particles: protons carry a +1 unit charge, electrons carry a −1 unit charge, and neutrons carry no electric charge.
Protons and neutrons together make up the dense central core called the nucleus. Electrons move in shells around this nucleus; neutrons do not orbit and are not in the outer shells.
The neutron was discovered by James Chadwick in 1932. Its mass is very close to that of a proton (about 1 atomic mass unit), which is why the mass number of an atom equals the sum of protons and neutrons.
Hence, the correct statement is that neutrons have no charge and are found in the nucleus of an atom.
