On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which described elements according to both weight and valence.

Within 16 years, chemists discovered the three missing elements scandium, gallium, and germanium.
