Dmitri MendeleevDmitri MendeleevDmitri Mendeleev is the scientists that worked with decks of cards to decelop the arrangement of elements on the periodic table in the 1860's.
mendeleev's name for a column of elements was groups.
The first scientist to make a successful arrangement of elements into a periodic table of the elements was Dimitri Mendeleev. He arranged his elements in order of increasing atomic mass. However, there were some problems with that arrangement. Henry Moseley corrected those problems by arranging the elements in order of increasing atomic number. This is the arrangement we use today.
Mendeleev arranged the elements according to their atomic weight and valence.
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.=
Chemical elements arrangement was the object of study for Mendeleev.

The periodic table of Mendeleev is a rational system of arrangement of chemical elements.

The arrangement of chemical elements into the widely recognised periodic table was first devised by the Russian chemist Dimitri Mendeleev.
