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.
Everyone knows it is a fact that the Picts painted and/or tattooed themselves with woad. The problem is that we don't know this at all. This one of the most pervasive unsubstantiated ideas about them, yet even well educated Celtic scholars will casually note this as a fact.ither copper or iron can produce a blue pigment, both being much closer to the color of the vitrum glass that Caesar noted than the Indigo of woad. The color is more attractive and the pigment more usable either for a body paint or a tattoo ink.
