What is the similarities in the modern periodic table and Mendeleev's table?
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.=
How does mendeleevs periodic table differ from moselys periodic table?
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.

What did Dmitri Mendeleev arrange into a systematic chart?
the periodic table of elements In this table, elements having similar chemical properties are stacked up. The chemical properties are determined by how many free bonds an atom has open, which is related to how many electrons are in that element's outer shell.
