Answer 1

Step-by-step explanation:

The main difference between Mendeleev and Modern period table is that Mendeleev's periodic table orders the elements based on their atomic mass whereas Modern periodic table orders the elements based on their atomic number.

Mendeleev's periodic law states that the physical and chemical properties of the elements are a periodic function of their atomic weights while Modern periodic law states that physical and chemical properties of elements are a periodic function of their numbers.
