For ionic compounds we write formulae in which there is an overall neutral charge, meaning that we balance the charges of the cations(+) and anions() to give an overall charge of zero. Monoatomic cations take the name of the parent element. Polyatomics: In general, anything with ate or ite at the end has oxygen in it; the ates have more oxygen atoms than the ites. Be aware of the hypo-ite, ite, ate and per-ate series for the oxyanions of chlorine this can be applied to bromine and iodine also. Note Hydrogen carbonate vs Carbonate the addition of a hydrogen atom is often seen and the nomenclature usually follows the simple rule of adding hydrogen to the start of the name and...
