Day --

Hi class,

I waited in the classroom for fifteen minutes after school ended, but no one showed-up. If you have any questions, you can email me anytime before 10 pm.

As a reminder, the Midterm will consist of questions only from the Midterm Review Sheet and Homework 24. There will be matching and multiple choice questions. All definition are matching, but don't forget to study the definitions on Homework 24.

Please bring me your calculator fifteen minutes before the exam. If you do not bring me your calculator before the exam. Checking your calculator will cut into your exam time.

Good Luck!

·      Electromagnetic Spectrum

·      Energy of a Quantum/Photon

·      Bohr’s Model of the Atom

·      Heisenberg Uncertainty Principle

·      Quantum Mechanical Model

·      Periodic Table

·      Electron Configuration

·      Energy-Orbital Diagrams

·      Electron Dot Structures (s and p blocks only)

·      Periodic Trends

Here are blank copies of Quiz4, Quiz5, and Quiz6.
Below are the answer keys to Quiz4, Quiz5, and Quiz6.

Day 64

Hi class,

Please begin to prepare for the exam on chapters 4-6, which has now been pushed to Tuesday. This exam will not be pushed back again.

Day 63

Hi class,

Please begin to prepare for the exam on chapters 4-6, which has been pushed to Monday. We will go over homework 6-2 tomorrow.

Day 59

Hi class,

Due to Bonding Day, the quiz will be tomorrow (Friday).

Day 58

Hi class,

Please prepare for the quiz tomorrow.

Do not worry about determining the number of valence electrons for elements in the d or f blocks. I did not properly explain this, so it will not be on the quiz.

Day 57

Hi class,

Tomorrow will be a review day, so please be prepared to ask questions. The quiz will now be on Thursday instead of Wednesday.

Day 56

Hi class,

There are no new assignments for tonight. Start preparing for the quiz.

Day 55

Hi class,

The homework due Monday includes problems 4 and 5 on page 181, problems 21-25 on page 160, problems 26-28 on page 162, and problems 8-10 on page 186. For problem 21, please provide the electron configuration, the energy/orbital diagram, and the number of unpaired electrons for each element.

For problems 8 and 9, use the following information that wasn't covered in class. Generally, the valence electrons are the electrons that are not in the noble-gas core when writing the condensed configuration for the element. Exceptions: If the element is in the s or p-block, do not count electrons in the d or f block as valence electrons. If the element is in the d block, do not count electrons in the f block as valence electrons. Examples: Bromine has seven valence electrons. (You should already know this because group 17 elements have seven valence electrons.) Iridium has nine valence electrons.

The quiz will be on Wednesday.

Day 54

Hi class,

Please read chapter 6 section 2 if you haven't already done so. The homework problems for chapter 5 section 3 are 26-28. The homework for chapter 6 section 1, chapter 5 section 3, and chapter 6 section 2 will be due on Monday.

Day 7

Hi class,

For class on Monday, please read chapter 2 section 2. Since one student in the class still doesn't have a textbook, the textbook pages are located at the end of this post. Fifth period seemed to struggle with the concepts presented today, so I recommend that the students in that section reread chapter 2 section 1 before reading chapter 2 section 2. I will try to clarify section 1 on Monday before starting section 2. Students in both sections should make sure they know the seven SI base units and the nine SI prefixes from class. Also, I didn't have enough time to show the video about the scale of the universe during fifth period, but here is a link to an interactive scale of the universe.

The homework for chapter 2 section 1 are practice problems 1-3 on page 38 and problems 1 and 2 under the label "section 1" on page 977. Before beginning the homework for this section, make sure you understand the example problem on page 38. All homework for chapter 2 will be due on Thursday, August 29. You need to show all your work on the homework problems.

The distribution and key for the first quiz are posted below. As a reminder, if you have any questions about the quiz, I will be in the library during lunch on Monday. DO NOT MISPLACE YOUR QUIZZES!!! Edline should be up and running on Monday.

Grade Distribution for Quiz 1
100+ (A) 7 students
94-99 (A) 5 students
85-93 (B) 6 students
75-84 (C) 1 student
68-74 (D) 0 students
0-67 (F) 1 student
