84 Chapter 13 Objectives You should be able to explain the origin of the term "alkaline earth" briefly relate how and by whom the alkaline earth metals were discovered describe the process by which the Curies isolated radium rationalize the trends in radii, ionization energies, electron affinities, and electronegativities of the group rationalize, on the basis of standard reduction potentials, why the alkaline earths are good reducing agents describe the general nature of the hydrides, oxides, hydroxides, and halides of the group list and briefly rationalize the ways in which beryllium is different from its heavier congeners list and briefly rationalize the ways in which beryllium is similar to aluminum briefly describe the role of the alkaline earths in beryllium disease, neutron production, nuclear fission products, metallurgy, fireworks, x-ray technology, and hard water describe how limestone and marble structures are damaged by acid rain briefly describe and represent the Solvay process briefly describe and represent the use of calcium carbonate in smokestack scrubbers briefly list some other uses of calcium carbonate briefly describe the use of calcium oxide (quicklime) in the steel and glass industries and in acetylene production briefly describe the use of calcium hydroxide (slaked lime) as a mortar, for water treatment, in the paper and pulp industries, and for bleaches list several uses of calcium sulfate
