LINKTOR Chemistry Molecular Model Kit (239 Pieces), Student or Teacher Set for Organic and Inorganic Chemistry Learning, Motivate Enthusiasm for Learning and Raising Space Imagination

• FOR BASIC TEACHING TO CHEMIST: 240 pieces molecular model kit, including 86 atoms, 153 bonds and a disconnector tool. It is a good assistant for high school students to study inorganic chemistry, organic chemistry, and structural chemistry.
• 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 86 atoms, 153 chemical bonds and a disconnector tool, with a total of 240 parts. Particularly suitable for beginners in chemistry and high school teaching of Inorganic Chemistry, Organic Chemistry and Structural Chemistry. There are two 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. Our guarantee If you have any doubts, please let us know by email. We will reply to you as soon as possible. If there are any problems after buying, we will provide refund or refund service. Directions The LINKTOR Chemistry Molecular Model Kit comes with 240 pieces, including 86 atoms, 153 bonds, and a disconnector tool. To use the kit, follow these steps: 1. Familiarize yourself with the universal standard color adopted for each atom. 2. Use the spheres to represent atoms and sticks to represent chemical bonds in the ball-and-stick models. 3. In the space-filling models, use the spheres drawn to scale and next to one another to represent atoms in real molecules. 4. Use the disconnector tool to easily assemble and disassemble the atoms and bonds. 5. Demonstrate fundamental molecular geometry, chemical molecular structure, and stereochemistry with 3D modeling studies.
