Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the electron configurations of various transition metals, categorize them based on predicted oxidation states and explain how these states relate to their electron configurations.

💡 Hint: Look for the stability in half-filled or fully filled conditions.

Challenge 2 Hard

Calculate the energy levels of electrons as they fill in transition metals and explain how this affects their reactions with ligands in coordination complexes.

💡 Hint: Consider how ligand type affects the energy of d orbitals.
