Drawing Lewis Structures:
1. Draw skeletal structure of compound showing what atoms are bonded to each other. Put least
electronegative element in the center.
2. Count total number of valence e-. Add 1 for each negative charge. Subtract 1 for each positive
charge.
3. Complete an octet for all atoms except hydrogen
4. If structure contains too many electrons, form double and triple bonds on central atom as needed.
Draw Lewis Structures for the following compounds.
1. F2
6. CO
2. H2O
7. CO32-
3. SCl2
8. SO42-
4. AsF3
9. N2F2
5. SiH4
10. C3H6O
