There are two rules to follow when writing formulas for ionic compounds. One has to do with charges and the other has to do with which atom to write first and which one to write second. What are these two rules?
The overall charge on the compound must be positve.
The overall charge on the compound must be negative.
The overall charge on the compound must be zero.
Positive ions come first.
Negative ions come first.
