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.
Tues 11/21
We took a Naming Quiz today and the rest of the time was used as work time to catch up on anything you still need to get finished.
Here are some more Lewis structures to practice if you want to hone your skills:
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.
Answer Key for More Practice with Lewis Dot Structures
And here is some more practice with naming ionic compounds and balancing equations:
Mon 11/20
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.
Thur and Fri 11/16 and 11/17
We looked at Molecular Geometries today.
Tues and Wed 11/14 and 11/15
Today we will continue to practice Lewis Structures and then start the Molecular Models Lab.
Mon 11/13
Today we will spend a bit of time talking about two things:
Nomenclature -- Ionic vs. Covalent Compounds
Lewis Structures. These are drawings that you see representing chemical compounds. We will learn how to draw these from the formula of a covalent compound.
Notes on Molecular Nomenclature and Lewis Structures (PowerPoint Notes)
Wed and Thur 11/8 and 11/9
Today we spent a good amount of time going over Weekly Practice 2.3
Afterward, we started these Notes on Ionic vs. Covalent naming and Lewis Structures
Mon and Tues 11/6 & 11/7
Today we will finish going over these Notes on Balancing Chemical Equations and Ionic Nomenclature and have some time to go over Weekly Practice 2.3
PowerPoint Notes covering ionic nomenclature and charge balancing
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; and Covalent Compounds). We haven't covered covalent compounds yet, but we will by next week.
Tue 10/31
Today we went over Weekly Practice 2.2
With any remaining time, students worked on the Single Replacement Lab and Metal Activity Series This lab will be due Th/Fri 11/9 and 11/10

Mon 10/30
We went over Activity series notes today and discussed single replacement reactions in detail.
Tue/Wed 10/24 and 10/25
In order to get all of my classes back on the same page we will be doing things a little differently for the even and odd classes. Last week the even classes ended up working on this Ionic Nomenclature Guided Learning Activity Odd classes will work on this on Tuesdsay.
Last week the odd classes worked on Notes on Balancing Chemical Equations and Ionic Nomenclature.
Even classes will go over these notes and start to practice balancing chemical equations.
Mon 10/23
Weekly Practice 2.1 Due today
Be ready to go over weekly practice and take the weekly quiz 2.1
If time we will also start looking at our next lab:
Single Replacement Lab and Metal Activity Series
Th/Fri 10/19 and 10/20
Today we'll spend some time wrapping up and practicing the material covered over the last couple of class meetings.
The new material for the day is balancing the overall chemical equation (in addition to the charge balancing we have already covered) and we will also look at ionic nomenclature--chemistry's way of saying "naming ionic compounds."
Ionic Nomenclature Guided Learning Activity-- to start writing down your rules for naming the different types of ionic compounds(Representative Ions--Grps 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.
Bonus (but not optional) HW Assignment: For those three rxns from the lab, balance the overall equation AND name the products that were produced. (These three complete reactions and the rest of lab work you did initially should be turned in with your weekly practice on Monday.)
Notes on Balancing Chemical Equations and Ionic Nomenclature
Tues/ Wed 10/17 and 10/18
Today we finished up our Chemical Reaction Type Notes
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.
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.
Bonus (but not optional) HW Assignment: Pick three rxns from the lab and predict products using the appropriate rxn type pattern and then try and charge balance the new ionic products you created in those reactions.
Mon 10/16
Today in class we'll go over the ideas that you came up with during the lab last week. 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.
Th/Fri 10/12 and 10/13
No weekly practice this week...the lab will take its place.
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.
Lab questions are due next class period! (This is unusual, but we will be using them in the next class.)
Tues/Wed 10/10 and 10/11
UNIT 1 TEST TODAY Remember on unit tests you will only be allowed to use one of the green periodic tables in my room and a calculator. You will not be allowed to use your notes.
No Weekly Practice this week...the lab will take its place this week since we only meet twice.
Th/Fr 10/5 and 10/6
Weekly Practice 1.4 --DUE TODAY
Atomic Spectra Activity is DUE TODAY

Tue/Wed 10/3 and 10/4
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
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.

Today we will go over the weekly practice 1.2 and wrap up our Notes on Periodic Trends. We will take our weekly quiz if there is time.
Th/Fri 9/28 and 9/29
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
Tue/ Wed 9/26 and 9/27
Today we will wrap up our Notes on Periodic Trends and start a discussion about electron configurations with this Electron Configuration Guided Learning
Th / Fri 9/21 and 9/22
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 Monday. (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?
Tues / Wed 9/19 and 9/20
Today is a work day for you to work on your Zeff Analogy Assignment and your weekly practie.
Zeff Analogy Activity:
We will model effective nuclear charge in class today and spend some time creating your own analogy similar (but different) to the one we discussed in class. 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. Zeff Analogy Example
Number of protons
Shielding electrons
Distance from nucleus
First two electrons (with no shielding)
Valence shell electrons
Mon 9/17
Weekly Practice 1.2 (Remember the answer key is in my room if you get stuck)
Weekly Quiz 1.1
After the quiz we will be finishing up our discussion of 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
Next Class Period:
During Tuesday and Wednesday of this week, I am going to give you some work time to work on your homework and the assignment below.
We will 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

First two electrons (with no shielding)
Valence shell electrons
Thur/Fri 9/14 and 9/15
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 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
Tue/Wed 9/12 and 9/13
Proficiency Opportunity: Bohr Model 1
Today we will continue our look at isotopes by going over some isotope example problems. The majority of what we do today will be looking at Average Atomic Mass and how it is calculated. We'll do the Guided Learning WS on Average Atomic Mass. (if not finished in class, you should attempt to finish the remainder of the questions before the next class period)
Make sure to bring a copy of the periodic table to the next class period.
Mon 9/11

Thur/Fri 9/7 and 9/8
Today we will aim to accomplish a number of things:
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 a few more things about the way the class will work this year and how things like homework, quizzes/tests, and labs will be run.
Start our first unit on Atomic Structure. By the end of the class, you should be able to look at the Periodic Table and/or element symbols for the atoms and determine the number of protons, electrons, and neutrons the atom contains.
Tuesday 9/5 and Wednesday 9/6
For homework, I would like you to answer these Chemistry Introduction Questions
Mon 10/2
Come to class prepared to go over WP 1.3 and take the weekly quiz.
Weekly Practice 1.4 --you will want to get a jump on this weekly practice as it is due on Thu/Fri instead of Monday. Our first unit test will be next Monday so we will spend Th/Fri of this week going over this homework.
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 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. :)
This is the last week of the Atomic Structure Unit. 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 to work on. Use the Chemistry Test Review --- Self Evaluation to help guide this process. Your Self-Evaluation is DUE with your weekly practice on Th/Fri.
