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 colour of metals such as silver and gold is mainly due to absorption of light when a d electron jumps to an s orbital. For silver, the 4 d â5 s transition has an energy corresponding to ultraviolet light, so frequencies in the visible band are not absorbed.ith a single 6 s electron, you might expect gold to be highly reactive; after all, c sium has the same 6 s 1 outer shell, and it is the most alkaline of natural elements: it explodes if dropped in water, and even reacts with ice.
