Question
How did Mendeleev change the order of elements in his periodic table?
Answer
Mendeleev changed the order of some elements based on their chemical properties rather than strictly by atomic mass. This allowed him to group elements with similar properties together, which improved the organization of the periodic table.
Explanation
This answer is strong because it directly addresses how Mendeleev prioritized chemical properties over atomic mass, demonstrating an understanding of the historical development of the periodic table. The question tests recall of Mendeleev's contributions.
Common mistake
Mendeleev's Element Order
Students often think Mendeleev only arranged elements by atomic weight without considering their chemical properties.
Emphasize that Mendeleev prioritized chemical properties over atomic weight when rearranging elements in his periodic table.
