In chemistry lectures we have little time to discuss the history of chemistry. This simulation begins with the development of valence concepts in the 19th century. We will step back into the 19th century to see how theories of chemical combination changed during that time.
Two years ago, Michael Morgan contributed an independent study on coordination compounds using Werner Jørgenson Bond Theory and Evolution of Bond Theory. Michael has recently updated this activity, AP Chemistry Post-Exam Activity: Coordination Compounds & Complex Ions. ChemEd X thanks Michael for his contribution describing how he has used two of our products.
Until June 17, 2017 these two titles are made available without subscription so that you may readily consider adopting these actvities for your own classroom. To access the free version (no different from the subscriber only version), use the links below. And remember to thank Michael by commenting at his blog about your experience using his contribution.
