An atom is composed of protons (+1 charge), neutrons (0 charge), and electrons (−1 charge). An atom has a neutral charge (total charge =0). An atom loses several electrons to become an ion, and the result is a charge of +3. How can this ion become neutral? 3 protons and 3 electrons 3 protons and 3 electrons 3 neutrons 3 neutrons 3 protons 3 protons 3 electrons 3 electrons
