| As you read the web-based assignment for Lewis Dot Structures, the following questions are offered as guidelines to help you maximize your efforts. It is very important for you to attempt Lewis Dot Structures for the problems listed in question 8. |
| 1. Lewis Dot Structures are very specific with regards to what they are intended to represent. What is the purpose of Lewis Dot Structures? What information will they not provide? |
| 2. What is the purpose of Valence Shell Electron Pair Repulsion Theory (VSEPR)? |
| 3. What is the Octet Rule? |
| 4. What are the individual steps, or procedures, that are used when preparing Lewis Dot Structures? |
| 5. What factors need to be considered when determining what atom will appear at the center of the structure? |
| 6. One element is a consistent exception to the application of the Octet Rule. Which element is it and why is it the exception? |
| 7. What is resonance and why is it important to a structure? |
| 8. Once you have completed the presentation on Lewis Dot Structures, you should be able to prepare Lewis Dot Structures for the following systems. |
A) SbBr3 |
B) CS2 |
C) TeO3 |
D) Cl2O |
E) NO3-1 |
F) SO4-2 |
| 9. Which of the substances that you have prepared Lewis Dot Structures for in question 8 will undergo resonance? In each resonating case, how many different resonance forms exist? |
