These are the ions and the charges: Al+3 SO3-2
The charges have to add up to zero, so two +3 aluminum ions cancel out three -2 sulfite ions: Al+3 Al+3 SO3-2 SO3-2 SO3-2
Simplify: Al2(SO3)3
For Aluminum sulfide we have a metal (Al) and a non-metal (S). That means we have a binary ionic compound.
Use the Periodic Table to find the ionic charge for Al and S.
Balance the charges so the overall (net) charge is zero.
