The first list of elements and their characteristics was written by?
French geologist Alexandre-Emile Béguyer de Chancourtois noticed that the elements, when ordered by their atomic weights, displayed similar properties at regular intervals. In 1862, he devised a three-dimensional chart, named the "telluric helix", after the element tellurium, which fell near the center of his diagram. With the elements arranged in a spiral on a cylinder by order of increasing atomic weight, de Chancourtois saw that elements with similar properties lined up vertically. The original paper from Chancourtois in "Comptes Rendus de l'Académie des Sciences" did not include a chart and used geological rather than chemical terms. In 1863, he extended his work by including a chart and adding ions and compounds.

In 1869, Russian chemist Dmitri Mendeleev arranged 63 elements by increasing atomic weight in several columns, noting recurring chemical properties across them.

Mendeleev widely distributed printed broadsheets of the table to various chemists in Russia and abroad.
History of the periodic table
French geologist Alexandre-Emile Béguyer de Chancourtois was the first to notice that certain elements displayed similar properties when sorted by atomic weight in increasing order. He published these findings in 1863, including a chart of elements, ions and compounds. In 1869, the first official periodic table of elements and their characteristics was created by Russian chemist Dmitri Mendeleev, who widely distributed his work to chemists in Russia and abroad.
