Potassium oxide, or K2O, is another example of an ionic compound. You may have noticed that unlike the sodium chloride example, which has one sodium ion for each chlorine ion, this time there are two potassium atoms for each oxygen. This is because the charges have to be balanced for the ionic compound.
The name of the compound is then aluminum oxide. When an ionic compound contains a transition metal, the names become a bit. more complicated. The metals in the d and f blocks can have more than one. charge and can thus form more than one compound. For example, iron and. chlorine form two different compounds, FeCl.
