29 Atoms, Molecules, and Solids Lectures by James L. Pazun Copyright © 2012 Pearson Education, Inc. publishing as Addison-Wesley
Goals for Chapter 29 To see probability as the correct description of electrons in atoms. To study atomic structure. To see atoms combine to make molecules. To categorize the structure and properties of solids. To study semiconductors and see their utility in electronic devices. To examine the phenomenon of superconductivity.

Copyright © 2012 Pearson Education, Inc. publishing as Addison-Wesley Superconductivity Superconductivity is a state where electricity passes a substance with no resistance, hence no heating and therefore, no loss. It is a difficult engineering problem right now because these materials are ceramic and would not make good wiring material. Refer to Conceptual Analysis 29.3
