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.=
Elements that have similar chemical properties occupy the same group on the Periodic Table.
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
Because in the table the elements are arranged into "periods", elements belonging to the same period have similar physical/chemical properties. This in tern reflects the fact that they have a similar number of outer shell electrons.
By grouping the elements on the Periodic Table.
The periodic table was not 'identified.' It is simply all known elements ordered by similar qualities and atomic number, among other things.
