Names of common polyatomic ions
WitrynaNaming Polyatomic Ions. At first glance, the nomenclature of the polyatomic negative ions in the table above seems hopeless. There are several general rules, however, that can bring some order out of this apparent chaos. The name of the ion usually ends in either -ite or -ate. The -ite ending indicates a low oxidation state. WitrynaAlright, let's continue on. One more set of polyatomic ions to know. So we have CrO four two minus, which is called Chromate. And if we have two Chromiums, so Cr two O seven two minus this is called Dichromate. Next, C two O four two minus is called the Oxalate ion. and we have O two, two minus is called Peroxide.
