LINKTOR Organic and Inorganic Chemistry Molecular Structure Model Set with Electron Cloud Models for Student and Experiments 444-Piece Teaching,

Basic Instruction for Advanced Science: A 440-molecule model kit containing 132 atoms, 158 bonds, and 150 copies of Carbon-60 (fullerene) is available for students from 7th grade through graduate level. Two chemical structure models: the ball-and-stick model uses spheres to represent atoms and sticks to represent chemical bonds, and the space-filling model, where spheres are drawn in atomic proportions and atoms are adjacent to each other as they are in real molecules. 3D Chemistry Educational Molecular Models: View chemical structures, molecular bonds, and bond angles in all directions. Demonstrate basic molecular structure, chemical molecular geometry, and stereochemistry through 3D modeling research. Easy to learn: The common standard adopted for the color of each atom makes it easy to use and learn. The atoms and chemical bonds are tightly and securely held together and can be easily broken apart with destructive tools. GUARANTEE: If you don't love it for any reason, we offer a full replacement or refund, no questions asked. If you have any questions, feel free to contact us. No need to worry, you can even share it with your friends. Try it now! Our amazing chemical molecular models contain 136 atoms, 158 chemical bonds, and a fullerene set (60 carbon atoms and 90 bonds), for a total of 444 components. LINKTOR's MM-444 chemical molecular models have nearly twice as many atoms and chemical bonds as similar products on the market. We offer three types of chemical models: 1. Ball-and-Stick Models. These 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 bonds. However, the relative sizes of the spheres do not always match the relative sizes of the atoms they represent. 2. Space-Filling Models However, in real molecules, atoms touch each other. Both of these disadvantages are overcome by space-filling models. The spheres are compressed, just as atoms are in real molecules. They are drawn to scale and adjacent to each other. The disadvantage of space-filling models is that the bond angles between atoms are difficult to understand. 3. Fullerene Model Fullerene is the third isomorph of the carbon element. Its structure resembles the masterpieces of architect Fuller, hence the name fullerene. Our Guarantee If you have any questions, please email us. We will get back to you as soon as possible.
