I had a workshop for joint meeting of the 22nd International Conference on Chemistry Education and the European Conference for Research in Chemical Education yesterday in Rome, Italy. My collaborator and I prepared materials for 40 people. But only around 10 people participated the event.
Before participants to make their bead models in this hands-on workshop, I gave a 30-min introductory talk about what can done with beads and particularly the connection of the bead model to the valence sphere model (VSM). I tried to emphasize that bead model is the best method to realize the VSM for both fullerenes and other molecules with sp3, dsp3 and d2sp3 hybridization.
