1.according to mendeleev's theory the physical and the chemical properties of an elements are the periodic functions of their atomic masses whereas according to modern theory physical and the chemical properties of an element are the periodic functions of their atomic no
2 .mendeleev's periodic table was based on hydrides and oxides of elements whereas modern periodic table is based on electronic configuration
3 mendeleev's periodic table had similar elements in different groups but different in same but in mod. all arrangements are proper
4isotopes were defined by mendeleev with different properties as their elements but in modern they are placed in same category as they have same at. no
5.nobel gases were not defined properly by mendeleev but there is a separate group for noble gasses (18th).
