Molecular Structure Model Kit, 974 PCS Molecular Ball Model, with Atomic/Charge-Cloud, Organic/Inorganic Model Kit for Student and Teacher, Modeling Science Kit for Space Imagination/Learning/Teaching
【974PCS New Version Learning Kit] It contains 408 atoms which are 11+ types of different elements (Please note that metal elements represent some of metal ions, such as sodium, so you can form NaCl); 530 bonds which contains different length to meet your needs and 36 Charge-Clouds. With this kit, you can build all common molecules and ions.
【Chemistry Teaching] What makes this kit unique is that it can build all the common geometries of metal complexes: octagonal, square planar, and trigonal bipyramidal and linear. Enough balls are included to make four models with any of these geometries allowing students to explore enantiomers and other stereoismers of metal complexes.
【Multifunctional Use] Carbon, oxygen, nitrogen, sulfur, phosphorous all have 4 tetrahedral holes, which allows to build these types of molecules and ions that have more than the normal valence( having positive formal charges).With this kit, you can not only build all the models other kits can build, you can also build structures other models can’t build like carbon monoxide (CO) and ammonium ion (NH4+)
【Cultivate Interest] This educational molecule modeling kit is designed for easy chemistry learning for organic, inorganic chemistry and functional groups. The color-coded bonds and atoms help visually demonstrate the geometry and structure of compounds & other bond types, let intangible chemical molecules atomic shape transform into tangible, help teachers and parents to cultivate children’s interest in chemistry, makes learning chemical 3D molecule or atomic structures fun and interactive.
【Eco-friendly Material】All materials of our 974PCS Organic Chemistry Model Kit are eco-friendly. Food-grade PVC, healthy and safe, no odor, and come with an configuration list to easily identify all atoms and connectors. Our atoms and bonds are kept in zipped bags to deliver in a sturdy large plastic box for easy storage and portability, as like picture 3(you can see the product picture and 11+ types of atoms elements and different length bonds).
