For this "Do the Review" episode, we explore the nature of the ionic bond, which is what forms when an atom that easily loses electrons is placed beside an atom that likes to gain electrons. Topics include the shell model, electron-dot structures, and effective nuclear charge. We also spend a bit of time answering off-topic questions from guest co-host JW. With this foundation, the discussion is extended to include the nature of the metallic bond. Duration: 49:47.
