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.
Sometimes it depends on how the light interacts not just with one molecule, but with a whole bunch of molecules. The colour of gold metal is only yellow when we have a large lot of gold atoms. Small particles of gold may be coloured purple or red. And we cannot really say what colour a single gold atom is.Sometimes the colour of an object does not depend on its molecules at all, but is a funny effect of its shape. It is possible for a regular shape pattern to make some wavelengths of light cancel themselves out.he colour of gold metal is only yellow when we have a large lot of gold atoms.
