AlCl3 is basically an ionic compound, but according to Fajan's rules, every ionic compound has some covalent character in it. From the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.Now Al3+ has high +ve charge on it, so it can distort the cl-cation easily, thus inducing covalent character into it.See Wikipedia for more details.rom the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.

Na is a metal, and Cl is a nonmetal, so you have an ionic compound when they form. As for covalent bonds, they take place between two nonmetals ONLY. For example, you have carbon dioxide (later you will learn why you have to put di-in front of oxide).luminium oxide Al2O3 is ionic because of the presence of the metal ion, Al3+ and non-metal ion O2-. Methane CH4 is covalent as all the elements in it are non-metals. It has carbon and hydrogen, both of them are non-metals.
