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

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.
