The correct statement is:
The total charge before and after the change remains the same, but the total atomic mass is different.
In a nuclear change (such as a nuclear reaction or decay), the number of protons and neutrons can change, which affects the atomic mass. However, the total electric charge (which is determined by the number of protons) will remain the same if the reaction involves conservation of charge.
