In mendelleevs table

Isotopes have similar chemical properties but different masses. Based on periodic law an isotope is an element which must have a separate place in periodic table. However there are ni places fir isotopes in Mendeleev periodic table. Since isotopes have same atomic number they haven't been given any specific position in modern period table.

In modern

Mendeleef’s periodic law was modified because atomic mass is not the fundamental property of element , Mosley gave the modern periodic law, according to this law,

The physical & chemical properties of the elements are periodic function of their atomic numbers

Answer 2
