This is the entire set of 22 models in (more or less) random order.  The formula is given with each picture for purposes of clarification of the number of atoms.  You WILL NOT be given the formula when you take the lab exam.  I hope this helps your studies of the models.

If you find any mistakes, or need help with one of the pictures, please let us know.
