But that’s not quite right either, because the German chemist Julius Lothar Meyer wrote down a very similar periodic system of elements a year earlier, with all the familiar groupings: the halogens, alkali metals, chalcogens and so on. He was contemporary and competitor of Dimitri Mendeleev to draw up the first periodic table of chemical elements. This cookie is set by GDPR Cookie Consent plugin.

Both had attended, in September 1860, the first international chemistry congress in. Both scientists had similar backgrounds: They had studied in Heidelberg, Germany, in the laboratory of the chemist Robert Bunsen. Because elemental indium is a silvery-white metal, however, Mendeleev postulated that the stoichiometry of its oxide was really In 2O 3 rather than InO. In 1870, German chemist Julius Lothar Meyer published a paper describing the same organization of elements as Mendeleev’s. He came from a medical family of Oldenburg. Meyer was virtually born into a scientific career. If this atomic mass were correct, then indium would have to be placed in the middle of the nonmetals, between arsenic (atomic mass 75) and selenium (atomic mass 78). Julius Lothar Meyer (18301895) and Dmitri Ivanovich Mendeleev (18341907) worked at the University of Heidelberg only five years apartboth under the direction of Robert Bunsen but they arrived there with significantly different backgrounds. The atomic mass of indium had originally been reported as 75.6, based on an assumed stoichiometry of InO for its oxide. The periodic table achieved its modern form through the work of the German chemist Julius Lothar Meyer (18301895) and the Russian chemist Dimitri Mendeleev (18341907), both of whom focused on the relationships between atomic mass and various physical and chemical properties. He discovered, for example, that the atomic masses previously reported for beryllium, indium, and uranium were incorrect. When the chemical properties of an element suggested that it might have been assigned the wrong place in earlier tables, Mendeleev carefully reexamined its atomic mass. \): Comparison of the Properties Predicted by Mendeleev in 1869 for eka-Aluminum and eka-Silicon with the Properties of Gallium (discovered in 1875) and Germanium (discovered in 1886).
