Day 70

Hi class,

Please read section 3 of chapter 7 for class on the Monday following Thanksgiving break.

For bonus points on the last exam, the reworked problems with explanations are due on Monday.

I hope you enjoyed the guest lecture on Friday. A 250-word summary of the lecture is due on the Tuesday following Thanksgiving break. If you were given an alternative assignment, a 500-word essay on your topic is due the same day. The document needs to be written in 12-point Times New Roman with 1-inch margins and double-spaced. The heading of the paper should read as follows:

Your Name
Teacher's Name
Course Name

Day 69

Hi class,

The homework for sections 1 and 2 of chapter 7 is due tomorrow during class. Mr. Christopher Bagwell will be giving a guest lecture. There will be an assignment on his lecture, so do not miss class.

Day 68

Hi class,

Please read section 2 of chapter 7 for class tomorrow.

Day 67

Hi class,

Please read section 1 of chapter 7 for class tomorrow.

Day 66

Hi class,

Please prepare for the exam on chapters 4-6 that will be administered tomorrow (Tuesday).

Day 65

Hi class,

The most effective way to study for the exam is to rework the last three quizzes and the homework on periodic trends. If you encounter trouble areas on the quizzes, refer back to the lecture slides and rework homework problems. If you have trouble with the homework on periodic trends, I can send you more problems to work for practice. If you have any questions about the exam, feel free to send me an email at mairaqayyum@gmail.com.

These are the topics that you need to know for the exam on Tuesday:

·      Law of Conservation of Mass

·      Electronic Charge

·      Nuclear Model of the Atom

·      Atomic number, mass number, atomic mass

·      Speed of Light

·      Electromagnetic Wave Relationship (speed of light = wavelength times frequency)

·      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 62

Hi class,

The homework on periodic trends is due in class tomorrow. I will hand back your quizzes tomorrow. Then, we will go over the quiz and the homework. Thursday will be a review day, so please bring any questions about the exam on chapters 4-6.

Day 61

Hi class,

Try to work as many of the homework problems as you can. We will finish chapter 6 section 3 tomorrow. The homework will be due on Wednesday. Thursday will be a review day. The exam on chapters 4-6 will be pushed to Friday.

Day 60

Hi class,

Please read chapter 6 section 3 for class on Monday. The homework for this section will be due on Tuesday. Wednesday will be a review day. The exam on chapters 4-6 will take place during class on Thursday.

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.
