<h3>What is electrical neutrality?</h3>
An atom is electrically neutral when the number of protons is equal to the number of electrons.
In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.
