Challenge Problems
Push your limits with advanced challenges
Given the electron configuration of a transition metal, identify its common oxidation states based on its filling order.
💡 Hint: Refer to how many d electrons are present and how they correspond to metal reactivity.
Explain how the instability of certain configurations leads to the preference for cation formation in transition metals.
💡 Hint: Relate back to half-filled vs. filled subshell stability.
