Challenge Problems

Push your limits with challenges.

Question 1

Assume you are Mendeleev in the 1860s. Discuss how you would justify leaving gaps in the Periodic Table for undiscovered elements and their predicted properties to your peers.

💡 Hint: Think scientifically about behavior and relationships, not just current knowledge.

Question 2

Critically assess how the inaccuracies in Mendeleev's atomic mass arrangement by modern standards impact our understanding of the Periodic Table.

💡 Hint: Consider how priorities in classification have shifted over time.
