Mendeleev treated the hydrides and oxides of element as the basic properties of elements for their classification.

Text Solution

Verified by Experts

During the time when Mendeleev gave his periodic table, atomic numbers and electronic configurations were not known. Comparison of properties of elements could be best done by comparing their compounds. He selected oxides and hydrides because oxygen and hydrogen form compounds with most of the elements due to their high reactivity.
