Product Details

Help students visualize molecular bonding while providing a hands-on model-building experience. This innovative kit utilizes “electron” chips and cut-out element symbols to build Lewis electron dot models for both atoms and molecules. Students are able to count and manipulate the electron “chips” for a variety of molecular structures and then draw the structures in the provided data tables. Detailed instructions guide students through the determination of valence electrons and the drawing of Lewis electron dot structures. Includes a magnetic wand and 100 wire-rimmed counting chips for teacher overhead demonstrations, 1,000 colored chips for student use, background information, instructions, data tables and reproducible masters for elements 1–18, plus extras of the common elements, such as H, C, O and N. Simplify the “not-so-simple” concept of molecular bonding—build Lewis electron dot structures!

Super Value Kit is complete for 30 students working individually. All materials are reusable.
