Answer:
The main differences are: the periodic table of Mendeleev is based on atomic mass. The current periodic table is based on the number of atoms. Noble gasses (as they are not found at that time) were not included in Mendeleev's periodic table. In Modern periodic table noble gases are in a separate group called group-18.
