Here’s something you should all have in your Chemistry classrooms.
This project was a mashup of two existing ones.
In 1969, Roy Alexander in the United States invented a helical periodic table with pop-out loops for the d-block and the f-block. It was by far the best way to visualise the periodic table at the time. His brilliant 1969 design patent is online here.
I blended these two ideas together and created a 3-dimensional periodic table with a g-block: Pyykkö’s elements in Alexander’s shape. The whole thing is about 30 cm high. I coloured all the elements by their electronegativities (where known).
Geography has globes, Biology has those limbless mannequins with their organs showing, and now Chemistry has this. It’s by far the most superior way to visualise the periodic table and electron configurations in 3D. It’s the only periodic table that puts all the elements in the right order without any gaps. It’s future-proof, fool-proof and waterproof.
