Which chemist is famous for creating the periodic table of elements?

Fact

Did you know?

Dmitri Mendeleev, a 19th-century Russian chemist, revolutionized chemistry by creating the periodic table of elements, organizing chemical elements by their atomic mass and chemical properties. His prediction of the existence and properties of new elements, which were discovered after his death, proved the accuracy of his table. The periodic table has become a fundamental tool in chemistry, used to predict the chemical behaviors of elements. Mendeleev is thus considered one of the greatest scientists of his time, having made an invaluable contribution to the understanding of the fundamental structure of the universe.
