【1416PCS New Version Learning Kit】Our chemistry structure kit contains 648 atoms made up of different elements; 768 bonds which contains different length to meet your needs. With this structure Kit, you can build all common molecules and ions.

【Chemistry Teaching】What makes this organic model kit unique is that it can build all the common geometries of metal complexes: octagonal, square planar, and trigonal bipyramidal and linear. There are enough balls to make four models with any of these geometries allowing students to explore enantiomers and other stereoismers of metal complexes.

【Multifunctional Use】Phosphorus, Carbon, Oxygen, Nitrogen, Sulfur, all have tetrahedral holes, which allows to build these types of molecules and ions that have more than the normal valence( having positive formal charges). With our molecular structure model kits, not only can you build all the models that other kits can build, but also you can build structures other models cant build like carbon monoxide(CO), ammonium ion(NH4+), [60]Fullerene(C60), etc.

【Cultivate Interest】This educational chemistry molecular model kit is designed for easy chemistry learning for organic, inorganic and functional groups. With Color Coded bonds and atoms to help visually understand and demonstrate the structure and geometry of compounds, let intangible chemical molecules atomic shape transform into tangible, helping teachers and parents to cultivate students interest in chemistry,makes learning chemical 3D molecule or atomic structures fun and interactive.

【High Quality Material】All materials of our 1416PCS organic chemistry model kit are healthy and safe, no odor, and come with an configuration list to easily identify all atoms and connectors. Delivered in a sturdy large plastic box for easy storage and portability.
