FINAL WEEK OF CH 151!!! :) Hang in there just a little bit longer because we are almost to the end!

This week we will explore the layout of electrons around atoms in molecules and understand how molecules get their unusual shapes. We will also explore how electrons are organized around the nucleus of an atom and briefly explore the four quantum numbers (which are used for the electrons). As always, if you have any questions, please let me know!

Here's what is due during week 4 of CH 151:

  • Explore the material in Chapter 3.3 - 3.5. There are several tools to help you learn the material.... they include:
  • Take Tuesday, July 15: Quiz #4
    • Quizzes will consist of several 'show your work' questions that will be completed in class. You will have 30 minutes to complete the quiz. You will have access to a periodic table (provided by me) and a calculator, but no notes are allowed.
    • Sample Quiz #4 (answers) might prove helpful while preparing for this quiz.
  • Take Wednesday, July 16 at 8 AM: The CH 151 Final Exam.
    • The final exam consists of 32 multiple choice questions and 3 short answer questions. Bring your calculator; you will have access to a periodic table (which I will provide), but notes are not allowed. You will be done with CH 151 by 10 AM on this day!
    • Please be aware: I do not return final exams to students. You will be able to see your grade soon after you take the Lecture Final but not your graded assignment.
