UNDERSTANDING ORES Most ores look like ordinary rocks. You would not guess that they contain shiny metal. The earth's crust is made up of many minerals. Minerals can be defined as naturally occuring chemical elements and compounds. People have discovered more than 2,000 different minerals. Many of these contain metals. But because the metal elements are linked with other elements in the minerals, the metals do not show all of their properties. Figure A 1. Most minerals are elements, compounds 2. In order to free the metal from the other elements, a mineral must be synthesized, decomposed Page 3 I ó Q + FUS

As minerals were formed from the molten magma, different ions occupied the same cites in the crystals. Lithium often occurs along with magnesium in minerals despite the difference in the charge on their ions. Suggest an explanation.
Carbon forms a number of allotropes, two of which are graphite and diamond. Silicon has a diamond structure. Why is there of allotrope of silicon with a graphite structure?
Materials containing the elements Y, Ba, Cu, and O that are superconductors (electrical resistance equals zero) at temperatures above that of liquid nitrogen were recently discovered. The structures of these materials are based on the perovskite structure. Were they to have the ideal perovskite structure, the superconductor would have the structure shown in pant (a) of the following figure. a. What is the formula of this ideal perovskite material? b. How is this structure related to the perovskite structure shown in Exercise 85? These materials, however, do not act as superconductors unless they are deficient in oxygen. The structure of the actual superconducting phase appears to be that shown in pan (b) of the figure. c. What is the formula of this material?

8.96 A business manager wants to provide a wider range of p- and n-type semiconductors as a strategy to enhance sales. You are the lead materials engineer assigned to communicate with this manager. How would you explain why there are more ways to build a p-type semiconductor from silicon than there are ways to build an n-type semiconductor from silicon?
