Ivy League universities have some of the largest university financial endowments in the world, which allows the universities to provide many resources for their academic programs and research endeavors.
Transition metal complexes have colour because the ligands bonding to the central metal atom or ion cause the d-orbitals to have different energies, that is, they are no longe â¦ r degenerate.In octahedral complexes, the dx2-y2 and the dz2 orbitals are higher in energy than the dxy, dxz and the dyz orbitals.ransition metal complexes have colour because the ligands bonding to the central metal atom or ion cause the d-orbitals to have different energies, that is, they are no longe â¦ r degenerate.
The strong colours of iron oxides are due to charge transfer, including in some cases, such as magnetite, charge transfer between iron(II) and iron(III) in slightly different environments. Intervalence charge transfer of this kind is also responsible for the extremely deep colour of Prussian Blue.ron(II) ion = green. Iron(III) ion = yellow. Rust (Iron oxide + water)= black or brown. Explain why the rust of iron is not green or yellow, but black or brown. Add your answer. Source.
