SOUJOY 444 Pcs Chemistry Molecular Model for Building Organic and Inorganic Structures, 3D Visual Science Learning Set with Atoms Bonds, Links and

Package: Include 444 pieces chemistry molecular model kit, including 132 atoms, 158 bonds and 150 parts for Carbon-60(Fullerene), you can now understand 3D complex molecule structures High Quality Material: SOUJOY Chemistry model kit is made of high quality PP and LDPE to manufacture, feel smooth, no scraps or cutting edges from the holes, easy to remove and put on 3D Visual Active Learning: This organic and inorganic model kit is designed for easy chemistry learning for organic, inorganic, ochem and functional groups, you can now understand 3D complex molecule structures with ease by building your favorite molecules with them Perfect Gift for Learning: Our chemistry kit is modeling simple and small to more advanced and complex chemical structures for schools and college level, students of all ages, researchers and enthusiasts Easy to Storage: The atom parts and links are color coded to national standards for ease of identification, and the pieces come in a slim plastic box for convenient storage The 444 pieces molecular model kit is designed for school teaching. It’s allows you to visualize the binds between atoms in three dimensions, the elements are represented by colored balls and the bonds by flexible rods, Each atom has the same number of holes as the number if valence electrons it needs to complete its outer shell. For example, Carbon has four electrons in its out shell, so it need four more to be complete. The black carbon ball has four holes, allowing it to form four four bonds and gain the electrons it needs. With this set you can demonstrate single bonds using the short white robs, and double or triple bonds using the long purple/grey blue robs. This molecular model kit enables users to build virtually simple and complex organic and inorganic molecules.
