The name of the compound formed from Aluminium and chlorine is Aluminium Chloride and the formula is AlCl₃.
- Aluminium chloride is also sometimes referred to as aluminium trichloride or aluminium (III) chloride.
- Aluminium chloride is an ionic compound made up of aluminium ions and chloride ions. Aluminium Ion has a valency of +3 whereas chloride Ion has a valency of −1.
What is Valency?
- The combining capacity of an atom is known as its valency.
- The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell
- So, in writing the formula, there is a cross of the two valencies because three chlorine atoms will have to react with one aluminium atom to gain one electron each.
Al³⁺ + 3Cl⁻¹ → AlCl₃
Thus we can conclude that when aluminium and chlorine combine , we get AlCl₃ which is called aluminium chloride
