Prefixes and Suffixes...
-ite
- Ending (suffix) is ONLY for polyatomic anions that contain oxygen, when the polyatomic ion is contained in the following....
- To distinguish -ite from -ate: memorize....but know that -ate polyatomic ions have one more oxygen than -ite polyatomic ions
- -the polyatomic anion alone
- Examples:
- BrO2- = bromite ion
- SO32- = sulfite ion
