Mendeleev of course only made use of existing information, merely arranged it a two-dimensional form.
# Relationships between the chemical and physical properties of families of elements # Holes in the table where as yet undiscovered elements were to be found. He found that the properties of an element were periodic and showed a pattern.
Based on this observation, he devised the table in such a way so as to arrange elements with similar chemical properties in columns forming groups.
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 arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
atomic weight
Mendeleev primarily used the element's atomic mass to classify them. He organized the elements into a periodic table based on their increasing atomic mass, allowing him to predict the properties of missing elements and arrange them in a logical order.

There are more elements and it's organized differently
atomic number Chemical elements are organized in the form of the periodic table of Mendeleev, in groups and periods.
Mendeleev organized the elements by increasing atomic mass and grouping elements with similar properties into columns called groups. He left gaps in the table for undiscovered elements and predicted properties of these elements based on the periodic pattern of known elements.

Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
atomic weight
The first periodic table was organized by Dmitri Mendeleev in 1869. Mendeleev arranged elements according to their atomic weight and properties, leaving gaps for unknown elements that were later discovered.
The Mendeleev table, also known as the periodic table, was organized by atomic number, atomic mass, and chemical properties of elements. Mendeleev was able to predict the properties of missing elements based on the gaps in his table.
Atomic number was not used by Mendeleev to organize his periodic table. He organized the elements based on their atomic mass and properties, leaving gaps for undiscovered elements that were later filled.
