Mendeleev periodic table is the basis for the modern periodic table that we use today. It has 65 known elements, but with the newly discovered elements, there are 103 elements in the modern periodic table. The key difference between Mendeleev and Modern periodic table is that the basis of the modern periodic table is mainly the electronic configuration of the elements, which we call as the atomic number whereas Mendeleev periodic table considers the atomic mass of the elements.
