- Apositive ion: add positive charge to the nucleus; negative ion: add an electron to the atom
- Bpositive ion: add positive charge to the nucleus; negative ion: remove positive charge from the nucleus
- Cpositive ion: remove an electron from the atom; negative ion: add an electron to the atom
- Dpositive ion: remove an electron from the atom; negative ion: remove positive charge from the nucleus
