Exploring the Bohr Model and Lewis Structures

This lesson covers the Bohr model and Lewis structure, teaching students how to write electron configurations and draw these models. It introduces key vocabulary related to atomic structure, explains the process of drawing Bohr models with examples like oxygen, and details the creation of Lewis structures, focusing on valence electrons and their role in chemical reactions.
