The Periodic Table is nature’s rosetta stone. To the uninitiated, it’s just 100-plus numbered boxes, each containing one or two letters, arranged with an odd, skewed symmetry.
To chemists, however, the periodic table reveals the organizing principles of matter, which is to say, the organizing principles of chemistry. At a fundamental level, all of chemistry is contained in the periodic table. That’s not to say, of course, that all of chemistry is obvious from the periodic table. Indeed, as John Emsley notes in his invaluable book, “Nature’s Building Blocks: An A–Z Guide to the Elements,” Mendeleyev never accepted that electrons came from atoms because he was convinced that atoms were indivisible.
