Very cool periodic table showing electron shells

Two teens in our local homeschool group are teaching a science class for kids aged 9-12. Last time, they handed out this very cool periodic table:


Instead of element symbols, electron configuration diagrams occupy the center of each element box. Running your finger (or eye) along row 5, for example, you can see why the palladium atom is smaller than the rhodium even though it has one more electron. I love it!

You can also find larger electron configuration diagrams for each element; they are indexed here.

This periodic table would make a great accompaniment to Mary Daly's Chemsitry 001 or other chemistry course. Also helpful when studying the physics of elementary particles.
