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.
Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded.
