Periodic Shuffle

No matter how you shuffle the elements, their electron configurations keep them in the same order. How can that be? Introduce the concept of periodicity through a lesson that combines inquiry, discussion, and comparison. Partners collaborate to puzzle through the similarities and difference in the chemical elements that are controlled by their electron configurations.
