Chapter 20 Metallurgy and the Chemistry of Metals This chapter is a review of the chemistry of non-transition metals. Upon completion of this chapter, your students should be able to: 1. Define the following terms: mineral ore metallurgy alloy gangue ferromagnetic amalgam band theory 2. List the three principle steps in recovery of metal from its ore and describe processes involved in each step. 3. Compare chemical reduction to electrolytic reduction and provide examples of each. 4. Describe the role that CaCO 3 plays in the purification of iron ore. 5. Describe distillation, electrolysis, and zone refine as methods for purification of metals. 6. Describe the ease of electron movement from valance band to conduction band in metals, semiconductors, conductors and insulators. 7. Explain why the doping of a semiconductor with certain impurities results in n-type semiconductors while doping with other impurities result in p-type semiconductors. 8. List five common properties of metals. 9. Predict the trends of the following properties for alkali metals as one progresses down the periodic table: density
