A polyatomic ion is seen as a molecule that has been ionized by gaining or losing electrons. In a polyatomic ion, the group of covalently bonded atoms carries a net charge because the total number of electrons in the molecule is not equal to the total number of protons in the molecule. Take up the quiz below to see how much you understood about the ions.
