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 |
