The famous scientist who developed the periodic table is Dmitri Mendeleev. In 1869, he created the first widely recognized periodic table by organizing chemical elements according to their atomic mass and properties. Mendeleev recognized that certain properties of elements recur periodically, which led him to arrange them in a tabular format. His work allowed for the prediction of undiscovered elements and their properties, thus advancing the field of chemistry significantly. Although the periodic table has undergone revisions and improvements since Mendeleev’s time, his foundational work remains critical to the study of chemistry.
