2. Uranyl ion (UO22) is commonly used ion, what sorts of function diffraction studies. Given that this is a relatively hard ion, what soes this behavior compare to that groups would you expect to be derived? How does this behavior compare to that 3. Match the three d-orbital energy-level diagras complexes [Fe(OH2)6]2+, [Fe(CN)6]4, and [FeCl4]2
