How can I write the formula for aluminum chloride?
February 20th, 2023
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##.
I hope this was helpful.
