I was wondering..

is chlorine diatomic?

if it is, can chlorine change from Cl₂ on the reactant side to Al(Cl₂)₃  in the equation of Aluminum Chloride?

Really al i'm wondering is if Aluminum Chloride is..
 
Al + 3Cl --> AlCl₃
or
4Al + 3Cl₂  --->  2Al₂Cl₃                              and why?  thanks

Chlorine is diatomic if it's by itself. Aluminum plus Chlorine would yield this:

2 Al + 3 Cl₂ = 2 AlCl₃
so it would yield this:
2 Al
AL is not diatomic
3 Cl₂
Chlorine is diatomic
2 AlCl₃
Aluminum has a charge of +3 and Chlorine has a charge of -1 so you need 3 Chlorine so balance it out which means AlCl3

remember HONClBrIF, it sounds like huncklebriff so it's easy to remember.

Hydrogen, Oxygen, Nitrogen, Chlorine, Bromine, Iodine, and Fluorine are all diatomic.

thank you so much honcllbriff is sweet
