Chemistry questions about writing formulas for ionic compounds!?
An example of an ionic compound that my teacher gave me: crupic nitrate which would be Cu+2 and No3^-1 which would then become Cu(No3)2 but why 2? The compound that I am currently trying to write is Aluminum sulfate. So I found out that sulfate would be So4^-2. because on the back of my periodic table it has names and charges of common ions but aluminum is not on the back of it. So when I flipped it over to the other side (the periodic table) I see that aluminum is Al but then how do I figure out if it is Al3 or what numbers it is supposed to have? How do I figure that out? Then after finding out what the charges are am I supposed to make them cancel each other out to make it equal to zero? Sorry for so many questions but I really need help! Thank you in advanced for your time! Thank you all so much you all helped a whole lot.
