The Periodic Table was first proposed by Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic weight and grouped them based on their chemical properties, noting that elements with similar properties occurred at regular intervals. Mendeleev's periodic table was a significant breakthrough, as it not only organized the known elements but also predicted the existence and properties of several undiscovered elements, which were later found and filled the gaps in the table.
