Atoms, Electrons and the Periodic Table
This 38-page resource is the first chapter in a college-level introductory chemistry reference text. A major objective of this chapter is to introduce the reader to 'the quantum way of thinking', and to show how this way of thinking led to a profound break with the past, and a shift in our way of viewing the world that has no parallel in Western intellectual history. It summarizes the major ideas of quantum theory that will be needed to treat atomic and molecular structure later on in this course. It covers the following basic quantum concepts: wave motion; energy units and magnitudes; and electromagnetic, continuous/thermal, line, and absorption spectra. Also included in this chapter is an explanation of how the arrangement of the periodic table of the elements must follow as a necessary consequence of the fundamental laws of the quantum behavior of matter. In this explanation, the following models of the atom are described: planetary, Bohr's, and shell.
