HERE IS UR ANSWER!

Merits Of Mendeleev's Periodic Table :-

1. He arranged the elements in rows called periods and columns called groups.
2. He also arranged elements based of their properties and atomic masses.
3. He helped find new elements as Mendeleev had left spaces of these probably yet to be discovered elements and even gave the properties of the same which were later found true.

Eg : Gallium (Eka- Al) and Germanium (Eka-Si)

4. His predictions came out successful.
