Answer 3

Dmitri Mendeleev

Dmitri Mendeleev was a Russian chemist who is best known for his formulation of the Periodic Law and the creation of the periodic table of elements.

Key Points about Dmitri Mendeleev: - Dmitri Mendeleev was born on February 8, 1834, in Tobolsk, Russia. - He is credited with the creation of the periodic table of elements, which he published in 1869. - Mendeleev's periodic table arranged elements by atomic mass and predicted the properties of elements yet to be discovered, leaving gaps for them in his table. - His work laid the foundation for the modern periodic table used today, which arranges elements by atomic number, rather than atomic mass as Mendeleev originally did.

Mendeleev's contributions to the field of chemistry have had a lasting impact and continue to be fundamental to the study of chemical elements and their properties.
