Does the atomic number changes when an ion is formed?
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.

Why atomic number not change during a chemical reaction?
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
