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.
Like most metals, finely divided gallium loses its luster and powdered gallium appears gray. Thus, when gallium is handled with bare hands, the extremely fine dispersion of liquid gallium droplets, which results from wetting skin with the metal, may appear as a gray skin stain.
