If you want to understand atomic spectroscopy, then it helps to have some understanding of the structure of an atom. In this General Chemistry Online eText, the authors give a thorough descriptive overview of atomic structure. This eText has sections on light particles and waves, the Bohr atom, the quantum atom, atomic electron configuration, and periodic properties. Additionally, this eText has interactive demonstrations of physiochemical principals that incorporate thought provoking questions. At the end of each section, flowcharts, called “concept maps” guide the students from basic principles to working concepts.
