The basic Concepts about the Principles of molecular shape made easy. This kit offers a lot of 3 dimensional Models with a visual appreciation of Molecular Bonding. You can demonstrate how the shapes of Molecules are determined by the number of bonds plus the lone parts in the valence shell of the center atom. Showing lone pairs a unique specialty with these models. To show the molecule based on tetrahedron you can make methane, for triangle by pyramid, you can make phosphorus pentachloride; and for octahedron you can build Sulphur hexaflouride and soon. Some of the structures: CO2, CH4, PCI5, SF6, NH3, H2O, BCl3. Sulphur ring SH Oxides of Nitrogen, Phosphorous P4 molecule, h2 SO4, Simple Complexes & many more.
Contents: Oxygen, Nitrogen, Sulphur, Phosphorous, Chlorine, Hydrogen, Covalent & Multiple (total components about 140 nos. within a smart plastic case. A teachers guide/instruction manual with full details on how to make all these models).
