【419PCS】Don't buy a defective kit from one of our competitors! Our Chemistry Molecular Model Kit was originally designed as a custom kit for a college professor who selected every piece carefully for use in his own classroom,it contains 179 atom pieces made up of different elements;155 medium-length hard bonds,25 long flexible bonds (good for double and triple bonds),30 V-bonds (for space-filling models);30 lone pair of electrons.With this set,you can build all common molecules and ions!
【Four Tetrahedral Holes in All Octet Rule Obeying Atoms】Our kit places 4 holes on all atoms with tetrahedral electron geometry: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 build structures other models cant build like carbon monoxide(CO) and ammonium ion(NH4+)
【Geometries of Metal Complexes】What makes this kit unique is that it also includes 4 of gray balls representing metals with 5 holes at 120 degree+90 and 4 of in a different shade of gray that are 6 holes at 90 degree,which 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.
【Non-Toxic Material】All materials of our 419PCS Organic Chemistry Model Kit are eco-friendly.Polypropylene atoms (pp plastic) feel smooth,no scraps or cutting edges from the holes;Low-Density Polyethylene links (LDPE plastic) are easy to remove and put on.The atom parts and links are color coded to national standards for ease of identification and come with an Instructional Guide to easily identify all atoms and connectors.Delivered in a sturdy plastic box for easy storage and portability!
【Making Chemistry Fun】This educational molecule modeling kit is designed for easy chemistry learning for organic,inorganic,o chem 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
