In 1869, Dmitri Mendeleev discovered the periodic law, which led to the creation of the Periodic Table of elements. He organized elements based on their Atomic Mass and chemical properties, revealing a periodic pattern that predicted the existence and properties of undiscovered elements. Mendeleev's work laid the foundation for modern chemistry and significantly advanced the understanding of elemental relationships.
