The kit makes basic concepts about the principles of molecular geometry easy to visualize and understand. This kit offer building of a large number of 3 dimensional molecular models with a visual appreciation of Molecular Bounding. Also demonstrates, how the shapes of molecules are determined by the number of bonds plus the lone pairs in the valence shell of the center atom. Showing lone pairs is a unique specialty with these models. For showing the molecules based on tetrahedron you can make methane. For triangle by pyramid, you can make phosphorus pentachloride; and for octahedron you can build Sulphur hexafluoride and soon,

Some of the structures that can be easily built include:CO , CH , PCI , SF , NH , H O, 2 4 5 6 3 2 BCI , Sulphur ring SH, oxides of Nitrogen, Phosphorous P Molecule, H SO , simple 3 4 2 4 and complex structures, and many more.

Contents: Oxygen, Nitrogen, Sulphur, Phosphorous, Chlorine, Hydrogen, Covalent & Multiple (total components about 140 Nos., packed in a suitable plastic case. Also includes a teachers guide/instruction manual with full details on how to make all these model and more.
