Enduring Understanding (s): Electron positioning is crucial to chemical stability. _________________________________________________
Essential Question (s): Explain the early models of the atom and how they relate to the Quantum-mechanical model. What does an electron configuration tell you about an atom? What is the connection between the valence electrons of an atom and a Lewis Electron dot diagram? _______________________________________________________
