The oxides we'll be looking at are:
Na2O | MgO | Al2O3 | SiO2 | P4O10 | SO3 | Cl2O7 |
P4O6 | SO2 | Cl2O |
Those oxides in the top row are known as the highest oxides of the various elements. These are the oxides where the Period 3 elements are in their highest oxidation states. In these oxides, all the outer electrons in the Period 3 element are being involved in the bonding - from just the one with sodium, to all seven of chlorine's outer electrons.
