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
How to DRAW Ionic Bonds Example: Lithium and Oxygen 4. Draw the bond, using arrows to show the transfer of electrons Li Li O
YOUR TURN TO PRACTICE Draw the bond for each 1. Potassium and Fluorine 2. Magnesium and Iodine
