 The Path to the Periodic TableThe path to the periodic table began early in the 19th century, when John Dalton united the atomic theory of matter, which had existed in various forms since antiquity, with the concept of the chemical element, which had emerged in the late 18th century with the work of Antoine-Laurent Lavoisier and his followers. |  Antoine-Laurent LavoisierLavoisier, a meticulous experimenter, revolutionized chemistry by establishing the law of conservation of mass, determining that combustion and respiration are caused by chemical reactions with what he named "oxygen," and helping systematize chemical nomenclature, among many other accomplishments. |  Julius Meyer and Dmitri MendeleevFor both Julius Meyer and Dmitri Mendeleev, writing a textbook proved to be the impetus for developing the periodic table—a device to present the more than 60 elements known at the time in an intelligible fashion. |
