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 compound that contains both covalent and ionic bonds is the compound of NH4Cl ( ammonium chloride). The Nitrogen atoms in combination with the Hydrogen atoms form the covalent bonds. The Ammonium ion (the cation) and Chlorine ion (the anion) form the ionic bonds of the polyatomic ionic combination.
