2. List and describe the factors that determine the feasibility of mining a particular ore at a particular site.
3. Use the periodic table to determine the number of electron available for bonding and explain the
trends in metal activity.
4. Explain why more active metals are more difficult to refine and process than less active metals.
5. Describe the process of oxidation-reduction and write balanced chemical equations for this process.
