97 Chapter 15 Objectives You should be able to: briefly describe the form in which some of the Group 4A elements were known to the ancients briefly relate how and by whom the remaining Group 4A elements were discovered outline the general manner in which the periodic law, uniqueness principle, inert pair effect, and the acid-base character of oxides are applicable to this group explain why catenation is much more prevalent in the carbon hydrides than it is in those of the heavier congeners, particularly silicon compare and contrast the incidence of pπ-pπ bonding in carbon compounds with pπ-dπ bonding in those of silicon compare and contrast the bonding in trimethyl- and trisilylamines describe why pπ-dπ bonding becomes important in Group 4A chemistry and will become more so going farther right in the third period describe the general nature of the group oxides, hydroxides, and halides compare and contrast the major allotropes of carbon describe the discovery and the modes of preparation of the fullerenes and nanotubes give some examples of elements that have been incorporated into fullerenes of various sizes list three types of reactions that the fullerenes undergo and give an example of each describe the structures, properties, and applications of the nanotubes briefly describe the role of the Group 4A elements in tin disease, radiochemical chronometry, and tracing methods describe several applications of carbon oxides; ionic, covalent, and interstitial carbides; carbon disulfide; and cyanides discuss some major applications of lead compounds including the storage battery discuss the general toxicology of lead compounds list, represent, and discuss the variety of silicates including the relationship of submicroscopic structures to macroscopic properties describe the structure and uses of aluminosilicates describe the nature of intrinsic, n-type, and p-type Group 4A semiconductors represent and describe the preparation of semiconductor-grade silicon describe the general nature of common, quartz, laboratory-grade, crystal, colored, photochromic, and fiber glasses
