An ion is an atom that has a net electrical charge because it has gained or lost electrons. If it has more electrons than protons, it is a negatively charged ion (anion). If it has fewer electrons than protons, it is a positively charged ion (cation). Therefore, an atom having more or fewer electrons than it should become an ion.
