PPT-Atom, Ion, or Isotope? Atoms

Atoms are neutral Protons Electrons There are special kinds of atoms Ions Isotopes Ions An Ion is an atom that has gained or lost ELECTRONS so it has an overall charge If an atom gains electrons its overall charge becomes negative If an atom loses electrons its overall charge becomes positive . ?.
