Molecular Geometry Set (VSEPR), Five universal VSEPR models allows the student to build linear, planar triangular, tetrahedral, trigonal bipyramidal, octahedral structures, When Student builds the molecules over a white paper and white links it can be easily visualized
Lewis structure Set, Help students determine the types of bonds in a substance, draw Lewis structures, and construct models of molecules, Chemists find the use of models helpful to construct Lewis structures and study covalent bonding
