WebIf a formula contains only one polyatomic ion, do not use parentheses around it. For example, NaNO 3, not Na(NO 3). If the formula contains more than one polyatomic ion, put the ion in parentheses and the subscript after the parentheses.

WebMost polyatomic ions are anions, meaning they have more electrons than the neutral atoms that are in the ion. Hydroxide (OH-) has one extra electron beyond what the neutral oxygen and hydrogen atoms would have. Although most are anions, there are some, which are cations. The most common is NH4+ (ammonium). WebLess Common Polyatomic Ions. The ions in this list, although less common than the first list, are still seen quite frequently in chemistry – so we suggest you learn these as well.
