Interpretation: The errors in the Mendeleev’s periodic table needs to be explained.
Concept introduction: Dmitri Mendeleev was the first to make a very significant contribution in the formation of the periodic table. He arranged the elements known at that time in the order of their atomic masses.

Answer to Problem 25A
The basis of Mendeleev’s periodic table is
Explanation of Solution
In Mendeleev’s periodic table, elements were not in correct order because the elements are organized using their atomic masses. Due to the arrangement using the atomic mass of elements, several elements were placed in groups of elements possessing different properties. The arrangement of elements based on
Taking atomic mass of an element for arrangement of elements is the error of Mendeleev’s periodic table.
