At first, he did it by Atomic Mass, but that didn't quite work out right, so he changed it to atomic number.
Periodic Table of Elements.
He "Dmitri" propose that the periodic table of elements that the elements should be grouped by rows and column and by atomic mass,
Dmitri Ivanovich Mendeleev created a periodic table to sort elements.
Some people have suggested that Dmitri Mendeleev did first organize elements in a periodic table in a dream.
Most chemists attribute the discovery to Dmtri Mendeleev.
63 elements were in Dmitri Mendeleev's First periodic table 63 elements were in Dmitri Mendeleev's First periodic table
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
Dmitri mendeleev arranged elements in order of increasing atomic masses. He considered chemical properties of the elements, their oxides and nitrides.
Dmitri Mendeleev is the scientist who is credited with first arranging and classifying elements into a chart that laid the foundation for the modern periodic table. Mendeleev's periodic table arranged elements by their atomic weight and predicted the properties of unknown elements that were yet to be discovered.
Dmitri Ivanovich Mendeleyev. Another spelling of his name is Dmitri Ivanovich Mendeleev.
Dmitri Mendeleev first periodic table is called Mendeleev's periodic table. Elements are arranged according to atomic mass.
