Which one of the following statements about the properties of neutrons is NOT correct?

Neutrons are subatomic particles found within the atomic nucleus alongside protons [1]. They possess a neutral electric charge, meaning they have zero charge. In terms of mass, neutrons are roughly equal to protons, though technically slightly more massive; both are approximately 1 atomic mass unit (amu), whereas electrons are significantly lighter [2]. The statement that neutrons revolve around the atomic nuclei is incorrect; it is the electrons that 'zoom' or revolve around the nucleus in specific shells or orbitals. Protons and neutrons are collectively known as nucleons because they are confined to the dense central region of the atom by the strong nuclear force [2]. Therefore, while options 1, 2, and 3 correctly describe neutron properties, option 4 describes the behavior of electrons.
