Advanced Chemistry Molecular Model Set, 2nd Edition

Buy Genuine MEGA MOLECULES MODELS. Fast Delivery! SAVE...SAVE....SAVE.....SAVE......SAVE.......SAVE!!! When learning to visualize 3-D molecular structures, isomerism, and nomenclature, these models are essential. This Advanced General and Organic Chemistry Molecular Model set has 180 components including 5 VSEPR models (linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral) and 1 square planar model for building complex ions. This model set has both flexible and rigid links which represent covalent bonds. The flexible links allow you to create single, double, and triple bonds. Rigid bonds allow for easy transformation between boat and chair conformations of cyclohexane. The bond lengths are scaled for accuracy. The instructions and pictures show you how to assemble the atom models. List of Parts: 36 WHITE HYDROGEN, 15 BLACK CARBON, 8 RED OXYGEN, 6 GREEN CHLORINE, 6 YELLOW FLUORINE, 6 ORANGE BROMINE, 6 PURPLE IODINE, 6 BLUE NITROGEN, 2 YELLOW SULFUR, 2 GREEN PHOSPHORUS, 1 SILVER ALKALI METAL, 1 SILVER ATOM - LINEAR, 1 SILVER ATOM - PLANAR TRIANGULAR, 1 SILVER ATOM - TETRAHEDRAL, 1 SILVER ATOM - TRIGONAL BIPYRAMIDAL, 1 SILVER ATOM - OCTAHEDRAL, 1 SILVER ATOM - SQUARE PLANAR, 36 GRAY LINKS FOR HYDROGEN SINGLE BONDS, 16 GRAY LINKS FOR SINGLE BONDS, 14 BLACK LINKS FOR CARBON-CARBON SINGLE BONDS, 14 GRAY LINKS FOR DOUBLE AND TRIPLE BONDS. The clear case has two snap closures which prevents spills. The case is divided into eight compartments to keep the atom models and bonds conveniently sorted. 21x11x3.5cm
