Why don't all compound names end with -ide?

Not all compound names end with "-ide" because this suffix is typically used for binary compounds, specifically those formed between two elements, where one is a nonmetal. Many compounds are more complex, such as those containing polyatomic ions (e.g., sulfate in sodium sulfate), which have different naming conventions. Additionally, compounds can also be classified as acids, bases, or salts, each having their own specific naming rules. Thus, the naming depends on the composition and structure of the compound.
