Answer:
Depends on what you are changing.
Explanation:
Protons have a positive (+) charge.
Neutrons have a neutral (0) charge.
Electrons have a negative (-) charge.
Since neutrons only affect atomic mass, we don't need to worry about it changing the charge.
If we had more protons than electrons, then since there are more + charges, the entire atom would be positively charged.
If we had more electrons than protons, then since there are more - charges, the entire atom would be negatively charged.
