A student explains that the atom most likely lost a neutron. – Describe one strength and one weakness of the student's explanation.

58. One strength of the explanation is that an atom's mass consists mostly of the mass of its protons and neutrons. Electrons have very little mass. So, the atom must have lost either a proton or neutron. One weakness, however, is that neutrons have no charge. So, removing the neutron should not affect the atom's charge. It is more likely that a proton was removed.
