The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.)

-- In Mendeleev's periodic table, transition elements were placed in another group.

--In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
