About this item:
FOR BASIC TEACHING TO ADVANCED SCIENCE: 444 pieces molecular model kit, including 132 atoms, 158 bonds, and 150 parts for Carbon-60(Fullerene), provides to students from Grade 7 to Graduate level. 
TWO CHEMICAL STRUCTURE MODELS: The ball-and-stick models use spheres to represent atoms and sticks to represent chemical bonds. In the space-filling model, the spheres are drawn to scale and are next to one another as atoms are in real molecules. 
CHEMISTRY EDUCATIONAL MOLECULE MODEL IN 3D: It can display chemical structure, molecular bond, and bond angle in all directions. Demonstrate fundamental molecular geometry, chemical molecular structure, and stereochemistry with 3D modeling studies. 
EASY TO LEARN: The universal standard adopted for each atom's color makes it easier for you to use and learn. Atoms and chemical bonds combine tightly and firmly and can be easily disassembled by disconnecting tools.
