The famous chemist known for his periodic table is Dmitri Mendeleev. Mendeleev, a Russian scientist, created the first widely recognized periodic table in 1869, organizing elements by their atomic mass and properties. His systematic approach allowed him to predict the properties of undiscovered elements, which later proved to be accurate. Mendeleev's work laid the foundation for modern chemistry and transformed the way scientists understand elements and their relationships. His periodic law and arrangement of elements are still fundamental in educational frameworks and scientific research today, showcasing his lasting impact on the field of chemistry.
