Practice

Now you should try your hand at working parts c, d, and e of exercise 16 in your workbook. The answers are shown in your workbook, but cover them up when you first try them. Then check your answers and compare your approach to the approach shown in the sequence of diagrams.

 

More Practice

After you have mastered the examples in exercise 16 using any of these methods, continue with the next set of practice problems.

Try your hand at drawing the electron dot diagrams for these compounds. (They are also shown in exercise 17 in your workbook.)

SO2 SO3 N2O N2O4

Note: S is in the center of the first two. A nitrogen atom is in the center of N2O. If you are interested, you might see how many possibilities you can come up with for that one. You might also try putting oxygen in the center if you would like. The two nitrogen atoms are in the center of N2O4.
