Know your sulfates from your sulfites, and your chlorates from your perchlorates? There are two "rules" that can be used for learning the nomenclature of polyatomic anions. Because these ions contain more than one atom, they are called polyatomic ions. Based on covalent bonding (next chapter) Charges of polyatomic ions are still based on the overall stability of the molecule Not as predictable as monatomic ions These will have to be memorized However, this becomes easy with practice Common Examples HCO32- Bicarbonate Ion PO43- Phosphate Ion NH4+ Ammonium Ion NO3- Nitrate Ion Objective 7 Name compounds containing a polyatomic … Patterns for Polyatomic Oxyanions.
