LINKTOR 444pcs Molecular Model Kit Chemistry Inorganic and Organic Structure Instructional Guide Building Atom Links Educational Toys Teaching Learning Set with A Fullerene Set for Teachers Students

• 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, 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.
• If you’re not in love with it for whatever reason, we’ll give you a full replacement or refund—no questions asked. If you have any doubt, please tell us. With nothing to worry about, or even to share with your friends, try it now.

Product description Our amazing chemical molecular model contains 132 atoms, 158 chemical bonds and a set of fullerene sets (60 carbon atoms and 90 bonds), with a total of 440 parts. Almost two times as much as the same product on the market. There are three kinds of chemical models that we can achieve: 1.Ball-and-stick models Ball-and-stick models use spheres to represent atoms and sticks to represent chemical bonds. The advantage of ball-and-stick models is that they show the correct angles between the bonds. However, the relative sizes of the spheres do not always match the relative sizes of the atoms they represent. 2.Space-filling models In real molecules, however, the atoms touch each other. Both of these disadvantages are overcome with space-filling models. in which the spheres are drawn to scale and are next to one another as atoms are in real molecules. The disadvantage of space-filling models is that the bond angles between atoms may be hard to see. 3.Fullerene models Fullerene is the third isomorphic body found in elemental carbon. The structure of fullerene is similar to the representative work of architect Fuller, so it is called fullerene. Our guarantee If you have any doubts, please let us know by email.
