Answer 1

Answer:

Mendeleev's classification of elements

Mendeleev's Periodic Table. Mendeleev arranged the elements based on their atomic masses. He observed that when the elements were arranged in increasing order of their atomic masses, there was a periodic recurrence in their physical and chemical properties.

Answer 2

Answer:

Mendeleev arranged elements in horizontal rows and vertical columns of a table in order of their increasing atomic weights in such a way that the elements with similar properties occupied the same vertical column or group. Mendeleev's system of classifying elements was more elaborate than that of Lothar Meyer's.
