With our trioxides and tetroxides, we've determined the number of oxygens and the charges associated with them. Now let's associate those structures with names. With our trioxides, we have borate, So borate would tell us that we're dealing with boron. So that would be BO3-3 carbonate carbon. So that's the CO3-2 that we discovered. Nitrate is dealing with a nitrogen, so NO3-1 and then silicate must be the silicon that we have here, SI, so SiO3-2. So this is their full polyatomic ion form with the name associated with it.
Now let's look at our Tetra oxides. So with our Tetra oxides we have phosphate which must be dealing with our phosphorus. So that is PO4-3 and then finally sulfate, which deals with our sulfur SO4-2. Now these represent our most common types of polyatomic oxyanion. And it's important to remember them as trioxides and Tetra oxides because from here we can slightly change their structures and introduce ourselves to new polyatomic ions and with them new names.
So click on the next video and let's take a look at some of these situations.
