Why it matters
Lavoisier listed 33 simple substances in 1789. Nineteenth-century researchers then explored arrangements based on atomic weights and recurring properties. Newlands and Lothar Meyer produced classifications in 1864, before Mendeleev’s 1869 table. These were stages of an evolving system; the modern ordering by atomic number came later.
