Answer:
The correct answers are : A neutron has no charge; Neutrons travel around the nucleus of an atom.
Step-by-step explanation:
The neutrons correspond to subatomic particles present in the nucleus of the atoms, together with the protons. Neutrons do not have an electric charge and have similar mass to protons. The difference in neutrons between atoms of the same element is called an isotope (they differ in mass numbers from one another, for example Hydrogen and Deuterium).
