Weekly Practice 4.2 This will be due on Monday and Tuesday after winter break.
Proficiency Opportunity:
Today we will be working on the Hydrated Salt Lab. I'll start class by giving some introduction to lab materials that we have not used yet in Chemistry. I will also give some information that can help guide you with your procedure and data collection. Make sure you have read the Error Analysis part of the checklist before you come to class...it will be helpful to think about as you work on the lab!
You will need to have the calculations done for this lab by next class or you will have a hard time following the error analysis through our work. The final lab write-up will be due as a group on the Wed/Thu of the week after break (Jan 9-10).

Here are some more lewis structures you can practice before the test on Thursday/Friday.
More Practice with Lewis Dot Structures There are a few in here that don't follow the octet rule. Some can go into hyperoctet like sulfur and phosphorous. And there are a couple that are still "happy" by not achieving a full 8 electrons. Boron and aluminum will be OK with only 3 bonds. And aluminum, even though it is considered a metal can still sometimes form a molecule.

Weekly Practice 2.3 There was a mistake on weekly practices this week. The one that was posted last week was supposed to be posted this week as the test review. The one posted here is actually supposed to be 2.2. I apologize for the confusion. You should still attempt to do the homework from this week, but don't worry if some of the questions seem a bit difficult. We will go over it in detail today.

Now that we have covered rxn types, charge balancing, and balancing equations you are able to write a complete BCE for double replacement reactions. The BCEs for six of the reactions from the Chemical Reactions Lab will be due this week on Friday and Monday along with your weekly practice. You should also indicate if reaction does or does not occur and try to name each of the new compounds that are produced
Today we will do a fairly quick lab looking at single replacement reactions and the Metal Activity Series.
Single Replacement Lab and Metal Activity Series
Charges for the transition metals in this lab: Fe +3, Cu +2, Ag +1, Zn +2. Also, remember that hydrogen gas is a diatomic so should be written as H2 (with the 2 being a subscript) when it becomes a product. You will need to keep track of hydrogen in the metal activity series as well.
You should also have start this Guided Learning that focuses on how we name compounds.
Naming Ionic Compounds Guided Learning This is homework and will be due on Tuesday/Wednesday of next week for my classes. As you work through the questions start thinking of rules for naming the different types of ionic compounds (Representative Ions-- Groups 1-2, 13-18; Polyatomic Ions; and Transition Metal Ions). Polyatomic ions are not covered in the worksheet, but once you get the other two...you can probably figure out what you need for polyatomic nomenclature. Take these rules you come up with and put them in the booklets we made today in class. Instructions are below if you forgot how to make the booklet.
Booklet and GL WS are due on Mon/Tue next week.

Today in class we'll go over the ideas that you came up with during the lab on Monday and Tuesday. Chemists have Five Reaction Types that describe the chemistry that happens in a wide range of reactions. We'll take a look at these five reaction types today and will practice using those reaction types to predict what the products of a chemical reaction will be. Over the next week or so, we will develop skills necessary to write out accurate and complete balanced chemical equations.
Before next class period students should write out 6 reactions correctly now that we know how double replacement reactions work. Be sure to leave some space between each chemical equation as we will need to fill in some information for each one.

We will use this lab to practice coming up with possible options and then will spend some time on Wednesday deciding which of our possibilities is the most reasonable and why.
Lab questions are due on Tuesday and Wednesday! (This is unusual, but we will be using them in the next class.)

Weekly Practice 1.4 --you will want to get a jump on this weekly practice as it is due on Wed/Thu when you come for the test.
There are a few questions on the Weekly Practice this week that are listed as "Challenge" problems. That does not indicate that they are optional but just is to let you know that they won't be an immediate piece of cake. Everyone needs to give them a try and have an idea down for all questions in order to get full credit. :)
Proficiency Opportunity: Scientific Notation 2
This is the last week of the Atomic Structure Unit. That means this coming Wed/Thu is the Unit Test. Remember that while you can use notes, homework, and other resources on the weekly quizzes...it is just you, the yellow PT, and your calculator on the end of unit tests. We need to take a few minutes and reflect on where we stand. Preparing for chemistry tests starts with thinking about what you have down pat and what you need work on. Use the Chemistry Test Review --- Self Evaluation to help guide this process. Your Self Evaluation is DUE with your test on Wed/Thu.
Class time today will be partially used to work a bit on Weekly Practice and partially time to ask questions that you have and start our review of Atomic Structure

Proficiency Opportunity: Bohr Model 2 and Electron Configuration 1
Today we will cover the question: How do we know about atomic structure?
Neils Bohr modeled the atom (we have used his model a bunch!) and ran some calculations about what you would see the electrons do when they were excited by high voltage electricity. We will look at the emission spectra of hydrogen and a few other elements and take a look at the light produced to provide evidence that our model of the atom is a pretty good one!

Weekly Practice 1.2 Due on Friday for Odd classes and next Monday for Even classes. (Remember the answer key is in my room if you get stuck)
During class today we will focus on "Periodic Trends" because they tend to change in predictable ways as you move across and down the PT. All of these trends can be explained with Effective Nuclear Charge, so you should not attempt to memorize these. Instead it will help you immensely if you can logically reason how Effective Nuclear Charge is causing each of them to change.
Watch the two videos below which demonstrate periodic trends.
Which periodic trend does this video demonstrate?
