Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carries a positive charge and has more protons than electrons. An anion carries a negative...

As long as the number of protons in an atom equals the number of electrons, the atom remains uncharged, or neutral. When an atom gains or loses electrons, it becomes an electrically charged ion. An atom that gains electrons becomes a negatively charged anion. An atom that loses electrons b...
