Feature: 1. VIBRANT COLORS: Molecular models are made up of colorful balls and connecting keys that are brightly colored, well crafted, and very safe from breakage. The common standard used for atomic color makes it easier to use and learn. 2. 3D MODELING: Molecular model demonstrates basic molecular structure through 3D modeling studies. It can display molecular structures, molecular bonds and bond angles in all directions. 3. BUILD MODELS: Chemistry molecular model can be used to build models of various common and slightly complex metals and molecular structures for teaching and laboratory use. 4. EASY TO LEARN: The molecule model is easy to learn, easy to store and easy to carry. Atoms and bonds are tightly and firmly bonded together and can be easily disassembled with a disconnecting tool. 5. APPLICABLE SCENE: The model kit is used in textbooks for the structural representation of various stones and metals molecules, which can enhance students' learning interest and teachers can explain it more visually.
