Answer:

Atoms are made up of protons, neutrons, and electrons. The mass of an atom is determined by the total number of neutrons and protons in the nucleus. The difference between an atom and an ion is the number of electrons. The change of electrons does not change the mass because electrons have a negligible mass. In other words, the mass of electrons is so small, it is considered insignificant.
