How the end of the chemical name is changed to distinguish an anion from its atom?

To distinguish an anion from its neutral atom in chemical nomenclature, the ending of the element's name is modified. For nonmetals, the suffix "-ide" is typically added to the root name of the element (e.g., chlorine becomes chloride). For polyatomic anions containing oxygen, the suffixes "-ate" or "-ite" are used, with "-ate" indicating a higher oxidation state (e.g., sulfate) and "-ite" indicating a lower oxidation state (e.g., sulfite).
