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

2. Chlorine Cl2 This is the finished Lewis dot structure
How did we get here?

3. O O N N DOUBLE bond TRIPLE bond atoms that share two e- pairs (4 e-)
atoms that share three e- pairs (6 e-)
N N

4. 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.

5. Let’s Practice!
Share & Check to make sure all the atoms are “happy”. Just use dots…no x H2

6. Let’s Practice!
Share & Check to make sure all the atoms are “happy”. Just use dots…no x O2

7. Let’s Practice!
Share & Check to make sure all the atoms are “happy”. Just use dots…no x
CH4

8. 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

9. Phosphate

10. The End
