Aluminum Chloride has a formula of #AlCl_3#. Aluminum typically is a cation and has an charge of #Al^(+3)#. Chlorine typically is an anion and has a charge #Cl^(-1)#. In order to bond ionically the charges must be equal and opposite. It will take three -1 chloride ions to balance one +3 aluminum ion forming an aluminum chloride molecule of #AlCl_3#.
