Part 3: Writing the Chemical Formula for Ionic Compounds
Ex. 1 Aluminum oxide
1. Write the ___________________ of the elements involved.
2. Write the ________________________________ to show the
stable ion that the element forms.
3. Use the __________________ – Write the ionic charges above
the symbols and crisscross the numbers so they are used as
___________________
4. The formula should have the _________________________.
