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
Easy to construct the three dimensional model of DNA. Emphasizing the base pair sequence and function of DNA, the sturdy, colorful bases snap together in the correct sequence, and the pairs attach to a center rod representing hydrogen bonds.
