What we did today:

1. Went over the 4 sheets that were due for homework. No key posted. Answered questions in class.

2. Handed back the scantrons that we filled out yesterday in class along with our review packets.

3. Went over/answered questions from the quiz from Friday.

Today was a shortened period, so we just went over the quiz.

Homework:

Study for our test tomorrow!!!! There will be no short answer on the test, making much more like our review packet, rather than our quiz.

(12-17-13)

Today we checked in:

• Unit 6 Review Packet

The key to the packet will be posted on moodle tonight.

Notes:

Look on moodle for the full notes. This is merely a quick summary of what we went over in class today.

Periodic Trends:

Atomic Radius. The size of the atom.

Ionization Energy. The amount of energy it takes to remove one of the outermost electrons (valence electron) from an atom.

Electronegativity. How “strong” an atom is at pulling bonded electrons closer to itself.

Get a partner. Get a scantron. GO OVER YOUR ANSWERS TO THE REVIEW PACKET AND FILL IN THE SCANTRON TOGETHER.

Class Blog of 12/16/13

Today we checked in:

• Coulombic Attractions
• Shells, subshells, and orbitals... Oh my!
• WK in our lab notebook with the periodic table

The keys to the handouts are on Moodle already

CORRECTION: Periodic Table Worksheet

6k) The answer is [Kr] 5S2 4D9

We picked up the periodic trends worksheets which can be found in the handouts link under Unit 6.

Class Notes:

Periodic Trends:

Atomic Radius:

-How big is an atom?

-How many energy shells are filled?

-How many protons are in the nucleus?

Ex. H             the first shell                                                             He           the first shell

      Li             the second shell                                                        O            the second shell

      Na           the third shell                                                            

As you go down in the periodic table, atoms get bigger because electrons are going into bigger and bigger shells that take more space farther away from the nucleus

As you go across in the periodic table, from left to right, atoms get smaller because there are a greater amount of protons for each electron thereby increasing the pull between them. This attraction pulls the electrons closer to the nucleus, decreasing the size of the atom.

-Atomic radius increases going down and to the left in the periodic table.

REMINDERS:

Test is THURSDAY!

The test will be 45 M/C with no short answers. 

The Unit Review Packet is due tomorrow!!!

The review session for this unit is WEDNESDAY at 7:00 A.M. 

Homework:
Finish the Periodic Trends worksheets. Due tomorrow.

Tomorrow's blogger will be Frankie

Today Ms. Friedmann was absent as were many other due to Snowball. We took at quiz and were given a packet that was labeled the Coulombic Attraction. This packet can be found under Handouts in Unit 6. This packet, along with homework due for today will be checked on Monday.

I will be the scribe again on Monday.

Have a good weekend!

We had a Late arrival today!!!

What did we do in class?

*Checked in the Homework and got one handout

           -Look in handouts for Quantum numbers wrkst #2

*Went over homework- Quantum Numbers and the first two pages of Electron Configuration and Orbital Diagrams

           -Check in the keys folder on moodle to see the answers

HW

1. The review packet is now due on Tuesday 12/17.  Our unit test will take place on Thursday, 12/19.

2. Plan for a quiz on everything in Unit 6 (so far) on FRIDAY of this week

3. The third page of Electron Configuration and Orbital Diagrams pages 

Class Blog 12/10/13

Right when we walking into class Mrs. F gave everyone a Band-aid and told us not to open it. We then all went to the back of the room and turned off the lights. On the count of three we all ripped our Band-Aids open, and if you were looking closely, you could see a small glow, or light, be given off.  It was a fun opening experiment at the beginning of class to get the day started about electrons and how they can give off light while jumping to different levels of energy in an atom. 

We then continued our notes from yesterday in our journals. They are posted in the Unit 6 Notes folder on moodle

The notes may be very confusing for you, but do not worry. Try the homework at home whether you understand it or not. This is a class were we need to get use to not getting it the first or second day. 


Classes were 40min today because of the Sports Assembly, so it was a shortened period 


Tuesday, 12/10 Homework

1) The worksheet "Electron Configurations and Orbital Diagrams" (posted in the Unit 6 Handouts folder) has 4 pages to it; do only the FIRST TWO pages for homework tonight.  I gave this out yesterday, but the handout is dated as today since I did not assign it until today.  Today's notes are posted in the Unit 6 Notes folder; they (and your text) should help you.  I will check in both tonight's homework and last night's homework (the Quantum Numbers worksheet) tomorrow in class.

2) Have you read "Bill Bryson -- The Mighty Atom" (posted in the Unit 6 Notes folder) yet?  You really should.

3) The review packet is now due on TUESDAY, 12/17, NOT TOMORROW.  Our unit test will take place on THURSDAY, 12/19.

4) Plan for a quiz on everything in Unit 6 (so far) on FRIDAY of this week (the lucky 13th).  :)

Enjoy your late arrival tomorrow!

The next blogger is Dorothy! Yay!

Today:

                We had a sub who took us to the Math Computer Lab, where we worked on a Rutherford Simulation Lab. If you were absent, check the handouts folder in moodle :)

We have lots of homework so make sure to complete the following for tomorrow:

- Rutherford simulation lab notes in journal (did in class, finish at home) pretty sure to check in
- 2 web assigns due at 11:59 PM... do them now. Stop procrastinating.
- Remember to complete your review packet due a week from today, do a little each night
- Take notes on the PowerPoints ON MOODLE, checking them in tomorrow

SO GO DO YOUR HOMEWORK AND GET SOME SLEEP!! GO CHEM!!

December 3, 2013

-First thing we did was we received a lesson about tests and lessons we should follow from Mrs. Friedmann.  

-Then we went over the test.

-We then began the new unit but did not get very far.

About the Test:

-The tests are much worse than what we are doing in class.

-We will have a new method of studying.

Future Lessons

-Advantages come with disadvantages, and disadvantages come with unexpected advantages. 

-Malcolm Gladwell

-Example: When people are more and more rich, the easier it is to parent and raise kids, however, it will begin to level off.  The richer it gets the harder it gets.  You can’t control them once they are powerful and independent.

-We are not using our given materials the way that it will help us.  You think you understand something just from understanding one problem and moving on.  You need to force yourself to understand it on your own.  Not just knowing the answer, you need to understand the answer and why you got the answer.  After understanding a problem, continue to work on similar problem until you understand it without using a key.

-Everything that comes with both advantages and disadvantages. Don't think you master something just because you get one right, consistency is key.

Future Tests

-DO THE REVIEW PACKET AND MORE PROBLEMS BEFORE YOU CHECK YOUR ANSWERS.

-We were given the review packet today and it will be due december 11th for credit.  There will be no video.  This way will force us to learn the material so we understand it not just a single problem.  Work on the review packet as we go through the unit bit by bit.

New unit: Atomic Theory and Periodicity

-The unit review packet is in moodle as well as the handouts.

-Notes

-This unit is on the atom.

-It all starts with the greeks

-first to have the idea of the atom

-in 400 BC the Greeks broke down matter into earth, air, water, and fire

-This is all we completed in class today.

Homework

-Two webassigns due wednesday night at 11:59 PM.

-Go on moodle and look at the two powerpoints and takes notes for tomorrow, they will be checked in THURSDAY because of a sub tomorrow. These are in the handouts folder about the history.

-Work on your review packet every day bit by bit until the end of the unit, due december 11th.
