Now, the Periodic Table of ControllersS

So there was the Periodic Table of Game Characters, and that spawned numerous imitators and spinoffs. Now we've graduated to the Periodic Table of Controllers: Console peripherals on top, handheld controls at the bottom.

Given my admittedly limited understanding of the actual periodic table, this arrangement would make the Sega Saturn the most reactive controller, and the Atari Pong controller the most inert. Hey, that actually almost fits. Share your science puns/coincidences in the comments.
