Mendeleev was one of a dozen or more chemists who aimed to create a classification of elements in the mid‐19th century. Mendeleev distinguished himself among the discoverers of the periodic system in their priority disputes because he was the only one who bothered to provide a clear definition of the entities to be ordered. This paper will first outline the role of Mendeleev's conceptual distinction between “element” and “simple substance” in the process of constructing the periodic table. Symmetrically, it will emphasize how the periodic system reconfigured the notion of the element as a relational entity, defined by its relations with other elements, a notion stabilized by the invention of the concept of isotopes in the early 20th century.
