John Newlands was a British chemist in the 1860s, a time when discovering elements was like collecting Pokémon—everyone was grabbing the new ones, but nobody knew how to organize them. Newlands noticed something weird: when he listed elements by atomic weight, every eighth element had similar properties. He called it the “Law of Octaves,” because, and I am not joking here, he compared it to musical scales.
Yes, he basically said, “Lithium, sodium, potassium—do-re-mi, baby.” Chemists at the time roasted him. One asked if he’d ever tried arranging elements alphabetically to get a better tune. Ouch. But here’s the kicker: he wasn’t wrong—he was just ahead of the curve by about a decade and a half.
The Octave of Awkwardness
Imagine presenting your big idea at a conference, and everyone rolls their eyes so hard they need medical attention. That was Newlands in 1866. He published his table, and the Royal Society rejected his paper, calling his pattern “arbitrary” and “like a game.” They literally said it wasn’t real science. Brutal. But here’s the surprising fact: Newlands was dead-on. The repeating pattern he saw? That’s what we now call periodicity—the whole reason the modern table works.
His only “mistake” was that he assumed all elements had been discovered, so his octaves had gaps. But when Mendeleev later predicted missing elements (like gallium), he built on the exact same foundation Newlands had laid. Mendeleev just had the nerve to fix the song instead of singing the wrong notes.
