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

• FOR BASIC TEACHING TO ADVANCED SCIENCE: 189 pieces molecular model kit, including 78 atoms, 111 bonds, provides to students from Grade 7 to Grade 12.
• 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 78 atoms, 111 chemical bonds. 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 Instructions for using the molecular modeling kit for chemistry: 1. Assemble the models of the chemical structure using the spheres to represent atoms and sticks chemical bonds. Thanks for your Use the universal standard for the color of each atom to facilitate use and learning. 3 pcs Use the educational molecular model of chemistry in 3D to display the chemical structure, molecular bond and binding angle in all directions. Thank you for your Demonstrate basic molecular geometry, chemical molecular structure, stereochemistry with 3D modeling studies.
