Nitrate, carbonate, phosphate, sulfate, nitrite, thiosulfate, perchlorate?

Explanation:

#NO_3^-#, #CO_3^(2-)#, #PO_4^(3-)#, #SO_4^(2-)#, #NO_2^-#, #S_2O_3^(2-)#, #ClO_4^-#. Do I win 5 pounds? In all of these examples the negative charge(s) formally lies on the oxygen atom - i.e. it lies on the most electronegative atom.
