He used mass,what they react to and there proertys
1)he arranged the table in periods and groups
2)he left space for undiscovered elements
3)he arranged the elements according to their atomic weight.
Atomic weight.
The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.

A Russian chemist named Dmitri Mendeleev wrote it and this periodic table was a table to illustrate recurring trends in the properties of elements.
This scientist is the Russian chemist Dimitri Mendeleev.
The usefulness of Mendeleev's periodic table was confirmed by the discovery of elements with predicted properties.
Mendeleev created a new row on the periodic table every time chemical properties were repeated.
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
dimitri mendeleev was the father of the periodic table of elements
what he meant by it was it meant the same as periodic table.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Both arrange elements in groups of elements having similar properties.
