Last days of 2nd quarter

Hi class
We have come to the end of the 2nd quarter. It seems the only thing left is the final exam. But before you get in the holiday spirit, remember you still have one more project due to me.
You all must get your science fair final papers handed in to me on Monday, December 17, 2007. All experiment must be concluded and data collected.Your assignment during the break is to work on your project boards.
Your boards are due on January 7, 2008. Science fair is scheduled for the following week. You have a letter for your parent informing them of this due date. It must be signed and returned to me on Monday.
I have included the letter in this email.

Hi Class,

We are using the same PowerPoint from last class (see October 19). We learned about the first 4 quantum numbers, and how to determine what they are:



1st Quantum Number: Principle Quantum number (n)- Energy Level, Whole number integer ranging from 1 to infinity



2nd Quantum number (L) ranges from zero to (n-1): Each numerical value corresponds to a letter, a shape and a maximum number of electrons



0 = s : 2 electrons maximum- This subshell is spherical

1 = p: 6 electrons maximum- This subshell is dumbbell shaped

2 = d: 10 electrons maximum- This subshell has 4 cloverleaf shaped orientations, and one that resembles a dumbbell with a doughnut.

3= f: 14 electrons maximum - This subshell has a shape that is not easy to depict in pictures.



3rd Quantum number (m l) -ranges from -l to +l



4th Quantum number (m s) - is either -1/2 or +1/2



Homework:

1. Give the values of n, ℓ, mℓ and ms for every orbital with n = 6.
2. Indicate whether the set of quantum numbers (n, ℓ, mℓ) exits or not.
a. 1, 1, 0
b. 5, 4, –3
c. 3, 2, –3
d. 6, 7, +7
e. 8, 1, 0
f. –2, 1, +1
g. 4, 2, –1
h. 7, 3, +4

3. Draw the shapes (including the orientation) of all the s, p and d orbitals.

4. Which orbital in each of the following pairs is higher in energy?
a. 5s or 5d
b. 4s or 3p
c. 6s or 4d

5. What is the maximum number of electrons in an atom that can have these quantum numbers?
a) n = 2
b) n = 3,
c) n = 3, l = 1
d) n = 4, l = 2
e) n = 5, l= 3, ml=3

August 8

Hi Class
Today you took the safety quiz. Many of you need to retake it. Remember you need to pass it with a 100%.

We learned the names and functions of some lab equipment, and your homework was to study for a quiz on the equipment on Friday.

August 6, 2007

Hi Class,
Today in class we reviewed the safety rules. You will have a quiz on the rules on Wednesday August 8. You must pass with a 100%. If you do not pass it on Wednesday, you must come in on your own time to retake the quiz, prior to performing any lab.

Today's Bell Ringer: Name 5 safe lab behaviors and 5 unsafe lab behaviors.

We review the scientific notation worksheet. If you are having trouble with scientific notation, make an appointment to see me.

After reviewing the lab safety rules I gave you a brief introduction to chemistry: What is chemistry, what are chemicals, why do we study chemistry?

Remember, binders will be collected on Tuesday, August 14 in anticipation of Parent Night.

Your homework, study lab safety rules for test on Wednesday. We will talk about lab equipment on Wednesday after test.

Recitation time will begin on Tuesday of next week.

Welcom Back

Welcome to school students. Hope you had a great summer.
Welcome to your homework blog site. Obviously you all found it OK as you are reading this message.
Today in class you received your syllabus, and we discussed my vision for the class. Remember, keep your textbooks at home for reference.
You all were given a worksheet on scientific notation. This is a critical math component for chemistry, and I felt a good place to start. We will go over it in class on Tuesday.
I hope you all remember your study group members, as these people will not only help you study, but will also be asked to pick up missed assignments for you when you are absent, as well as sources of any missed notes.
We also discussed the format of the class. The first hour will be devoted to new material. The remainder of the class will be a recitation, where you will get into your study groups and discuss the material we just covered, as well as start on homework. This schedule will NOT be followed on lab days. On lab days, the whole period will be devoted to lab.
On Tuesday, the worksheet must be completed, parental letter signed, and binders must be ready. Always bring binders, calculators, and pens to class.

See you next week, have a great weekend.
