Molecular Model Set (179 Pieces: 76 Atoms, 102 Bonds, 1 Open Key Tool) A complete student set for building and visualizing organic and inorganic molecules. The set contains all pieces needed to construct a wide range of molecular geometries and reaction intermediates, making abstract concepts tangible and easier to understand. Key benefits Makes learning chemistry concrete: Build three dimensional structures to visualize bond angles, molecular shapes, and spatial relationships that are hard to grasp from flat diagrams. Supports coursework and study: Ideal for classroom demonstrations, homework, lab preparation, and exam review for secondary and college chemistry courses. Ready to use and reusable: Pieces connect and disconnect repeatedly, allowing for many practice sessions and model variations without degrading performance. Simple to use: The included open key tool assists assembly and disassembly, reducing wear on small parts and speeding set up and transitions. What is included 76 atom pieces for representing different elements and positions in molecules 102 bond connectors for single, multiple, and variablelength connections 1 open key tool for safe and easy removal of bond connectors Total: 179 pieces Function and compatibility Designed for organic and inorganic molecular modeling and general chemistry instruction Compatible with typical classroom modeling activities and curriculum that require handson molecular construction Suitable for individual study, group lab work, and instructor demonstrations Design and performance notes Precisionshaped atom and bond components allow consistent connections and predictable geometry when building models Durable construction built for repeated assembly and disassembly during coursework Balanced piece count enables construction of small to moderately complex molecules while remaining portable and easy to manage Use scenarios Classroom demonstration: An instructor assembles models in front of the class to show VSEPR shapes, hybridization, and isomer relationships, then passes pieces to students for handson practice. Homework and selfstudy: A student builds reaction intermediates and conformers to check understanding of stereochemistry, bond rotations, and functional group orientations. Lab or project work: Small student teams construct molecular structures for reports or science fair projects to illustrate bonding patterns and molecular geometry. Who this is for school and college students studying organic and inorganic chemistry Teachers and tutors who need a reliable set for demonstrations and student practice Anyone learning or teaching molecular structure who benefits from handson visualization This 179piece molecular model set delivers the core components needed for clear, practical molecular modeling without unnecessary extras.
