The most important principle was the listing in groups, after similar chemical or physical properties.
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
Mendeleev organized the elements in his table by increasing atomic mass and grouping elements with similar properties together. He left gaps in his table for unknown elements and accurately predicted the properties of these missing elements based on the patterns he observed.
The properties were repeated after 8 elements.
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
Mendeleev realized that some elements had not been discovered.
Yes.
Chemical elements arrangement was the object of study for Mendeleev.
He "Dmitri" propose that the periodic table of elements that the elements should be grouped by rows and column and by atomic mass,

Dmitri Mendeleev was the first scientist to create the periodic table
Dmitri Mendeleev is credited with developing the periodic table of elements in 1869. He arranged the elements by increasing atomic mass, grouping together elements with similar properties. Mendeleev's table formed the basis for the modern periodic table.

mendeleev's name for a column of elements was groups.
The atomic theory was supported by Mendeleev when scientists discovered that elements displayed a periodic trend in their properties when arranged by increasing atomic weight. Mendeleev used this information to create the periodic table, organizing elements by their atomic weights and predicting the properties of missing elements.
