    Didn't look at the video, but the Wikipedia page has a collection of alternative periodic tables. I like the Janet left-step periodic table because it is in order of how the orbitals fill up. Chemists don't like it because Helium is not with the other noble gases, but I'd regard that as a small price to pay. It makes what's happening with the orbitals clear and that was a bit of a mystery to me in A-level chemistry.
