Steps in showing Ionic Bonding
1- Write the Lewis Dot structure for each of the elements.
2. - Draw an arrow (or more if needed) to show the transfer of electrons
3. -Determine the charge for each ion (oxidation number) and write it next to the
chemical symbol.
4 - Make sure the sum of the oxidation numbers is zero (balance the charges).
5.-Write the chemical formula
For each problem indicate if the elements are metals or nonmetals and then complete
the following Ionic Bonds showing all five steps listed above.
1. Potassium and Fluorine
2. Magnesium and Iodine
3. Sodium and Oxygen
4. Sodium and Chlorine
5. Calcium and Chlorine
6. Aluminum and Chlorine
