Mendeleev not only made the important connections of various elements with commonalities, but identified that gaps in the Table existed which presumably would be filled with the discovery of more elements, which they were. This was a stupendous and creative leap forward for science and he would undoubtedly have received a Nobel Prize for it had it existed at the time. One would think this deserves a song or so. And, of course, it has |

The neat and regular idea of how similar elements have similar properties is not as orthogonal as you would believe. Wiki - Periodic Table shows Hydrogen sitting on top of the Alkali metals. There are numerous other ways to present the table. One has a sort of circular presentation with layers and arms. |
