The following pictures are (more or less) in random order.  Included are the chemical formula for each next to the picture for the sake of clarity on (exactly) which model you are seeing depicted.  On the lab exam, you will NOT be given the formulas.

Following the pictures (at the bottom of the webpage) is a key for the names of the molecules.  If you find an error, or have a question about a picture, please let us know and we will try to correct it as soon as possible.

One printing of the entire webpage in black and white on a laser printer at the college took 17 pages total, so bear that in mind if you're going to try to print it for yourself at home or school.

We hope this helps your studies!
