IONIC Lewis Dot Diagrams Chemical BONDING IONIC Lewis Dot Diagrams

[Na]+1 [ Cl ]-1 Sodium Chloride This is the finished Lewis Dot Structure [Na]+1 [ Cl ]-1 How did we get here?

Practice Dot diagrams & formulas Lithium fluoride Magnesium oxide Calcium chloride Potassium hydride

Drawing molecules using Lewis Dot Structures Remember: atoms are sharing e- to complete their outer shell!

Simplest Covalent bond is in H2

F2 Valence orbital notation for each atom? Lewis Dot diagram for molecule?

Multiple Covalent Bonds Valence orbital notation for each atom? The overlap results in a DOUBLE BOND Lewis Dot Structure?

Multiple Covalent Bonds Valence orbital notation for each atom? The overlap results in a TRIPLE BOND Lewis Dot Structure?

Use Pencil Step 1 count total valence e- involved; this is your target number. No more! No less! Step 2 connect the atoms with single bonds **you may need to reconfigure the dots later… ahhhhh pencil Step 3 complete valence shells to make the atoms stable.

Let’s Practice! HCl CH4 NH3 make sure all the atoms are complete and stable. Just use dots…no x HCl CH4 NH3

Draw the Lewis Dot Diagram for polyatomic ions Same thing! Just add or subtract electrons based on the charge, enclose in a giant bracket and write its charge. REMEMBER! A negative charge means it has extra electrons! Phosphate
