Question
What was one significant outcome of Mendeleev's predictions about undiscovered elements?
Answer
One significant outcome was that the discovery of predicted elements, such as gallium and germanium, provided strong support for Mendeleev's periodic table. These elements had properties that matched Mendeleev's predictions, validating his approach.
Explanation
This answer is strong because it highlights the importance of Mendeleev's predictions and their validation through the discovery of new elements. The question tests understanding of how scientific predictions can support theories.
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.
