Background information,
lab procedure, student response form, and answer key available as a PDF.

As in the VSEPR I kit, the accompanying PDF explains the geometry of valence electron pairs, based on VSEPR theory, and molecular shape using ABE notation. Instructions are given for drawing correct Lewis structures of several molecules which can then be built with this kit.

In addition, the more advanced topic of orbital hybridization is covered.

The lab procedure for this kit gives students hands-on experience making models with linear, trigonal bipyramidal, T-, square pyramidal, and see-saw shapes.
