Electron orbital and shell board

thingiverse

One of the most challenging aspects of chemistry is comprehending how electrons revolve around the nucleus and fill their shells (S, P, D, and F). Adding spin (up or down) to model uncertainty only complicates matters. It was difficult for me to organize and process how to combine these various electron facets. I resolved this by merging an orbital diagram worksheet with multiple orbital diagrams to illustrate how electrons fill in order. A YouTube video titled "Orbitals" offers valuable insights: https://www.youtube.com/watch?v=cPDptc0wUYI. While filling out orbital diagrams can be a tedious task, I found a way to model the shell levels, numbers, and spin into one manipulative. If you have access to the Photographic Card Deck of the Elements (periodictable.com), you can utilize the cards to facilitate classroom study or challenge and review elements with this board. **THIS IS A WORK IN PROGRESS** This activity requires 118 marbles (16 mm in diameter). Finding decent-quality marbles with consistent sizes will significantly enhance the experience. This manipulative is ideal for AP Chemistry or College chemistry classes. Printing 2-6 sets per class enables small group activities, while speed games can be developed to assess students' understanding. The lesson plan will be available for purchase on TeacherPayTeacher.com.
