Matter, Atomic Structure, and Bonding: Valence and Core Electrons

We began the class period by creating a table of the data from yesterday’s Flame Test lab, which students then used to complete the Lesson 17 Worksheet.


We also reviewed the Lesson 17 PowerPoint before transitioning to Lesson 18.  There are several hand-outs for Lesson 18, including the Lesson 18 Worksheet, the Lesson 18 Shell Model, the Table of Electron Shells, and the Table of Valence and Core Electrons.  We reviewed the Lesson 18 PowerPoint through slide 9 and will complete the remaining slides tomorrow.  For homework, in addition to completing the Lesson 18 worksheet, students should work through questions #3-10 at the end of Lesson 18 in the textbook and then read through Lesson 19 in the textbook.
