Unformatted text preview: Museum were from Brisbane, hinting towards its large volumes of malachite present under its rocky desert surface. The reason that copper compounds tend to have co many different colors in it is due to the fact that they contain d-orbitals, which split into two sublevels. This split of energy levels is due to the fact that the ligands attach different ions in the copper compound. Thus, when the orbitals are split up, it gives rise to new, more complex ions, to attach to the levels and give off different colors. When an ion such as Ammonia (NH4) attaches to one of these energy levels, the blueish hue of the copper then turns slightly purple Bibliography: http://www.galleries.com/Minerals/Carbonat/MALACHIT/MALACHIT.htm http://www.gemstoneeducation.com/Malachite.htm...
