The ratio of the lons in an ionic compound depends on the charges of the ions. The amount of positive charge
must balance the amount of negative charge. For each compound, both the total positive charge and the total
negative charge will equal the LCM found in part B.
Determine the number of positive ions and the number of negative ions for each ionic compound in the table.
Use the lonic charges of each element you found in part A. The number of each ion times the charge on the lon
should equal the LCM determined for each cell in part B.
[# of ions of an element] * [lon charge) - least common multiple (LCM)
Drag each element's chemical symbol to the table to show how many lons are needed to balance the charges.
Each symbol will be used more than once. The first row is already completed for you.
