Proficiency Opportunity-- Naming and Balancing
Today we will be talking about Error Analysis--How did your error affect data, calculations, and the final result? This is an important skill to take away from Chemistry so we'll be working with it often in labs. Today we will focus on what you should and should not do in analyzing errors during a lab.
Work time for Hydrated Salt Lab
Tue/Wed 12/16 & 12/17
Tue/Wed 12/16 & 12/17
Proficiency Opportunity--Scientific Notation
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 complete the calculation for this lab by the next class, or you will have a hard time following 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).

Today we'll wrap up our notes on Intermolecular Forces.
For today's class, we will begin working on the Exploring Intermolecular Forces Lab. The pre-lab questions need to be completed before beginning the lab. You would also benefit from looking at the six properties that we are examining in the lab and determining how low or high IMAFs would change the properties.
Tue/Wed 11/18 & 11/19
Tue/Wed 11/18 & 11/19
Today we will be looking at the differences between polar bonds and polar molecules. Polarity causes some interesting interactions between molecules. We call these interactions Intermolecular Attractive Forces (IMAF). We will take a look at these IMAF's and their consequences today as well.
Notes on Molecular Polarity and Intermolecular Attractive Forces
We will be starting the Exploring Intermolecular Forces Lab next week The pre-lab questions will need to be completed before then.

Proficiency Opportunity: Electron Configuration and Bohr Model
Today, we will continue to practice Lewis Structures and then start the Molecular Models Lab.
We'll start this lab by focusing on what we already know: naming compounds and drawing Lewis Structures. We'll use the model kits to see how our drawings relate to our observations of the molecules in the real world. There will be a few columns on the lab that you won't be able to do yet, but we'll pick those up this week as we work.
Today we will also be taking a quick look at the difference in the bonds of ionic and covalent compounds. We'll use the Linus Pauling scale of electronegativity to distinguish between the bond types. This will also allow us to start thinking about the polarity of bonds.
Notes on Electronegativity and Bond Polarity

Naming Booklet As you work through the notes for naming, use the booklet we made in class (directions below if you still need to make one) to start writing down your rules for naming the different types of ionic compounds. Here are the pages to include in your booklet: (Representative Ions--Grps 1-2, 13-18; Polyatomic Ions; Transition Metal Ions.) For each page, list the rules you should follow for naming those types of ions and the exceptions to these rules. We will use the 4th page later, so don't put anything on that page yet.

Today we will cover the 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 the skills necessary to write out accurate and complete balanced chemical equations.
Tue and Wed 10/7 & 10/8
Tue and Wed 10/7 & 10/8
Today, we'll wrap up the lab from Monday.
We will also spend a bit of time talking about ionic compounds and going over a handy pattern on the periodic table that will help us quickly determine the charge of the ion that is formed when an atom gains or loses an electron. Once we know the charges of the ions, we'll learn how to determine the chemical formula of ionic compounds by charge balancing.

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 during the next class deciding which of our possibilities is the most reasonable and why.

Mon 9/29
Today we will review last week's homework and take the weekly quiz for 1.3.
This is the last week of the Atomic Structure Unit. That means this coming Thu/Fri 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 Thu/Fri

Proficiency Opportunity: Electron Configuration and Bohr Model
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 Animation Slide from class--you'll have to open this in PowerPoint and run the slide show to see the animation.
Atomic Spectra Activity--Lab Sheet (Due Thursday next week)
Atomic Spectra and Bohr Model Video
If you didn't get a good view of the hydrogen lamp spectra...here is a drawing of it.
Tue/Wed 9/23 & 9/24
Tue/Wed 9/23 & 9/24
Today we continued our discussion 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.
Notes from today: Quantum Model and Electron Configuration Smart Board Notes
Double Slit Experiment Video that was mentioned in class.
Here are some notes from a PowerPoint that discusses the quantum model of the atom in more detail than is needed in our course, but you may find helpful. Quantum Model PowerPoint

Th/Fri 9/18 & 9/19
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.
Proficiency Opportunity: Scientific Notation
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?

We will start today with 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.
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 properties that we will focus on in this class include:
Atomic radius (size)
Electronegativity
Ionization energy
Notes from today on Effective Nuclear Charge
Zeff Analogy Assignment:
We will also model effective nuclear charge in class today and spend some time creating your own analogy similar (but different) to the ones we discussed in class. Here is a good example, Led Zefflin Concert. Your model or drawing should be self-explanatory, but if you don't feel that all of the aspects below have been covered, you can 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

We will use what we found during the scavenger hunt to learn about the safety procedures and features in the room to make sure that everyone is safe in the lab.
Go over the way the class will work this year and how things like homework, quizzes/tests and labs will be run.
Finish with a "really tough" quiz.
As homework for this first week, students are to do the following things for the next scheduled class period:
If you haven't already, please fill out the Introduction to Chemistry Questions to show that you found the website and to give me some information about yourselves.
If you'd like, check out the course syllabus, it will be posted on the Syllabus page in Canvas.
We don't really use a textbook, but we do have one available as a resource that may be helpful at home. If that sounds like something that you might want to use at home, you can grab one from the library bookroom.
