Vsepr Ii Molecular Model Kit

Kit Contents: 4 red 4-peg oxygen atom centers 7 green 4-peg halogen atom centers 2 purple 5-peg phosphorous atom centers 2 silver 6-peg sulfur (xenon) atom centers 2 yellow 4-peg sulfur atom centers 12-1.25" PVC, clear bonds (single bonds) 12-1.625" PVC, clear bonds (double bonds) Background information booklet Lab procedure, student response form, and answer key As in the VSEPR I kit, the accompanying booklet 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.
