Today we'll spend some more time with the models from last class and will look at the three-dimensional shapes that they make. We will discuss how the Lewis structure can be used to predict this shape!
We'll work some on the Molecular Models Lab today. The lab is due MON/TUE of next week which is earlier than normal because of the long Thanksgiving weekend.
Wednesday 11/14 and Thursday 11/15
Proficiency Opportunities: Scientific Notation
Weekly Practice 3.2 Due Friday and Monday depending on your class.
Today we will be looking at the difference between ionic and covalent bonds. We will use a scale of electronegativity to distinguish between the bond types. This helps us to be able to start thinking about the polarity of bonds.
Electronegativity and Bond Polarity Notes
We will also spend some more time on Lewis Structures with this Molecular Models Lab The lab should be as complete as possible when you come to class on Friday/Monday. You should have everything on the table completed except the electron geometry and molecular geometry. Also try to answer as many of the questions on the bottom as you can. We will talk about the two geometries on Friday and Monday so that you can complete the entire lab by the end of the period.
Friday 11/9 and Tuesday 11/13
Weekly Practice 3.1 Due Today (come prepared for the weekly quiz)
After we go over the homework and take the quiz we will take a look at something called Lewis structures which is a way for us to draw a molecule that shows the atoms and bonds. We will draw these from the formula of a covalent compound.

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.
The test that was scheduled for next week is also being pushed back until after the long weekend. Today we will go over last week's weekly practice.
Tuesday 10/23 and Thursday 10/25
Wednesday 10/24 Since most of you will be taking the PSAT today, we will use today as a work day if you are in class.
Today we will review ionic naming and talk more about the Single Replacement Lab and Metal Activity Specifically we will discuss how to create a metal activity series.

We will spend the remaining time finishing the observations for this Single Replacement Lab and Metal Activity Series along with working on ionic naming Naming Ionic Compounds Guided Learning This is homework and will be due on Tuesday/Wednesday.
Wednesday 10/17 and Thursday 10/18
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.
Balancing Chemical Equations PowerPoint
Monday 10/15 and Tuesday 10/16
Today we will wrap up charge balancing and how to determine if double replacement reactions will occur. We will also start on how to balance an overall equation.

Thursday 10/11 and Friday 10/12
No Weekly Practice this week...the lab will take it's place this week since we only meet twice.
Proficiency Opportunity: Scientific Notation 3
We will spend the next day or so working towards writing complete and correct balanced chemical equations. We started today by looking at how ions are formed and how we charge balance new ionic compounds. We also learned how to use the solubility rules to determine if a reaction will occur or not.
After today you should be able to correctly predict and charge balance all of the products for the lab we worked on last week along with being able to use the solubility rules to determine if the reaction occurred.
PowerPoint Notes covering ionic nomenclature and charge balancing
Tuesday 10/9 and Wednesday 10/10
No Weekly Practice this week...the lab will take it's place this week since we only meet twice.
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.
Friday 10/5 and Monday 10/8
Today we will start to look at chemical reactions with this Chemical Reactions Lab This is a lab that encourages you to investigate a problem much like the first chemists did when they were trying to figure out how and why chemical reactions were occurring. 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.)
Wednesday 10/3 and Thursday 10/4
Unit 1 Test today
Weekly Practice 1.4 --DUE TODAY
Atomic Spectra Activity is DUE TODAY
Today we will spend some time reviewing during the first half of class. Come to class with your self evaluation sheet and any questions you have come up with. That will help make our review time more helpful for you!
We'll be taking the test for the unit during the second half of class.
Monday 10/1 and Tuesday 10/2
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
Thursday 9/27/18 and Friday 9/28/18
Weekly Practice 1.3 (Due Friday for even classes and Monday for odd classes)
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!
Atomic Spectra Activity (Due Wed/Thursday of next week)
Tuesday 9/25/18 and Wednesday 9/26/18
Today we talked about electron configurations which is basically a method of keeping track of all the electrons in an atom and where they are in the electron shells. We will use a tool called an Aufbau Diagram to help us determine the electron configuration for each element.
We also spent some time talking about the Quantum Model of the atom, which is our most accurate model of the atom to date.

Wednesday 9/19/18 and Thursday 9/20/18
Proficiency Opportunity: Scientific Notation
We will do a little review on how to use scientific notation. Here are some Scientific Notation Notes in case it has been a while since you thought about numbers in scientific notation to help you with this week's weekly practice.
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?
This next video is a fake, but it is still worth watching. What periodic trend does this video demonstrate?
Monday 9/17/18 and Tuesday 9/18/18
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)
We will spend the first 10 to 15 minutes of class to make sure everyone understands this Guided Learning WS on Average Atomic Mass. Afterwards, we will go over a few more practice problems with Average Atomic Mass Average Atomic Mass Notes.
Today we will be looking at the Periodic Table. Make sure you have a print out of the Periodic Table from the links above to bring to class today.
Today we will be looking at Effective Nuclear Charge (or Zeff). We will use Zeff to predict a variety of properties about atoms. The three that we will focus on in this class include:
atomic radius (size), electronegativity, and ionization energy
Notes from today on Effective Nuclear Charge
HOMEWORK: (due next class period)
We will model effective nuclear charge in class today and spend some time in class creating your own analogy similar (but different) to the ones we discussed in class. Here is a good example Led Zefflin Concert You will also need to include a short written explanation that discusses how these things are depicted in your analogy and how they affect or are affected by the effective nuclear charge. You can do this on the back of the assignment.
number of protons
shielding electrons
distance from nucleus
First two electrons (with no shielding)
valence shell electrons
Thursday 9/13/18 and Friday 9/14/18
