1. How to DRAW Ionic Bonds Example: Lithium and Oxygen
Draw the Lewis Structures for each
Determine the charge of your ions
Li +1 O -2
3. Criss-Cross the charges to count number of atoms needed
Li +1 O -2 = Li2O
This is the formula for the compound made during the bond. The 2 tells you that you need TWO atoms of lithium to complete the bond

2. How to DRAW Ionic Bonds Example: Lithium and Oxygen
4. Draw the bond, using arrows to show the transfer of electrons Li Li O

3. YOUR TURN TO PRACTICE Draw the bond for each 1. Potassium and Fluorine
2. Magnesium and Iodine
