Polyatomic Ions
Polyatomic ions are ions that consist of two or more atoms bonded together, which collectively carry a charge. They can be either positively charged (cations) or negatively charged (anions). Understanding polyatomic ions is essential for writing chemical formulas and balancing reactions, as they often appear in various compounds.

Chemical Formulas
Chemical formulas represent the composition of a substance using symbols for the elements and numerical subscripts to indicate the number of atoms. For polyatomic ions like sulfite, the formula must include the charge to convey the ion's overall electrical state. This is important for accurately describing compounds and predicting their reactivity.
