Reading Preparation
Textbook assignment: Read Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 7: Sections 4.
Study Notes
7.4 Ion Electron configurations: Here we simply need to keep track of how many electrons we have, since the number will differ from the ground state of the neutral atom.
There are no equations for these sections.
Web Lecture
Read the following weblecture before chat: Electron Configurations
Study Activity
Videos for Chapter 7: Electron Configurations
Review the Videos at Thinkwell Video Lessons.
- Under "Electron Configurations and Periodicity: Electron Spin and the Pauli Exclusion Principle"
- Electron Configurations through Neon
- Electron Configurations beyond Neon
Use the interactive site e-1 Configuration Instructions to work out the electron configurations for elements from each of the eight groups listed. Click to create the box notation, check the chemist shorthand notation, then check your answer.
OR
Use the Electron Configuration Matching Game to see whether you can match electron configurations with their elements.
Chat Preparation Activities
- Essay question: The Moodle forum for the session will assign a specific study question for you to prepare for chat. You need to read this question and post your answer before chat starts for this session.
- Mastery Exercise: The Moodle Mastery exercise for the chapter will contain sections related to our chat topic. Try to complete these before the chat starts, so that you can ask questions.
Chapter Quiz
- There is no chapter quiz YET.
Lab Work
LAB #5 GUIDED INQUIRY: Using two-phase chromatography separation of mixtures -- Phase II
Carry out the experiment you designed in phase I. Collect your data in an appropriate format, and perform all planned analysis. If you think your data is incomplete or inaccurate, and you have adequate supplies, repeat your procedure. If so directed, be prepared to share your data with your peers.
