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. Here are the instructions if you forgot how to make the packet.
PowerPoint Notes covering ionic nomenclature and charge balancing
10/17 Tuesday and 10/18 Wednesday
Today we will wrap up charge balancing and how to name compounds and predict products. We will also start on how to balance an overall equation.

Monday 10/16
Weekly Practice 2.1 Due on Friday for Odd classes and a week from Tuesday for Even classes.
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.

Wednesday 10/11 and Thursday 10/12
To start our new unit we discussed some of the ideas students came up with about how the reactants in the Chemical Reactions Lab might have reacted. Chemists use 5 reaction types to describe the chemistry that happens in a wide range of reactions. We took 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.
Before next class period students should write out 12 of the 24 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.
Monday 10/9/and Tuesday 10/10
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 time on Wednesday deciding which of our possibilities is the most reasonable and why.
Lab questions are due on Wednesday and Thursday of this week! (This is unusual, but we will be using them in the next class.)
Thursday 10/5 and Friday 10/6
Unit 1 Atomic Structure Test
Weekly Practice 1.4 and Self Review Guide due today
Tuesday 10/3 and Wednesday 10/4
Weekly Practice 1.4 This last Weekly Practice is a good review of the material we have covered in this unit. You should attempt to do all of the problems, even the ones labeled as "challenge" problems.
Proficiency Opportunity: Scientific Notation #2
Atomic Spectra Activity is due on Wednesday for odd classes.
Monday 10/2
This is the last week of the Atomic Structure Unit. The unit test will be on Thursday 10/5 for even classes and on Friday 10/6 for odd classes.
You will not be allowed to use your notes or homework on this test. It will be just you, a blue periodic table, and a calculator. Preparation for a chemistry test starts with thinking about everything we have covered so far and realizing what you have down pat and what you still need to work on. You can use the Chemistry Test Review --- Self Evaluation to help guide this process. Your Self Evaluation is DUE on the day you will be taking the test.
Weekly Practice 1.4 This last Weekly Practice is a good review of the material we have covered in this unit.
Friday 9/29 and Monday 10/2
Be ready to go over the Weekly Practice 1.3 which is due and take a short quiz on the material covered in the weekly practice.
Students will have more time to work on the Atomic Spectra Activity (Due Wed/Thursday of next week; October 5th or 6th )
Wednesday 9/27 and Thursday 9/28
Today we took a look at how we came to know about the atomic structure.
Neils Bohr modeled the atom and ran some calculations about what you would see the electrons do when they were excited by high voltage electricity. We will take a look at the emission spectra of hydrogen and a few other elements and take a look at the light produced that provides evidence that our model of the atom is a pretty good one!
We also continued with our discussion about electron configurations and practiced how to do one now using the Periodic Table.
Atomic Spectra Activity (Due Wed/Thursday of next week)
Monday 9/25 and Tuesday 9/26
Tuesday: Be prepared for a quiz on average atomic mass and atomic structure. Weekly Practice 1.2 is due today (Tuesday the 26th).
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.
Notes from today Quantum Model and Electron Configuration Smart Board Notes
Here are some notes from a PowerPoint that that discusses the quantum model of the atom in more detail than is needed in our course but you may find it helpful. Quantum Model PowerPoint
Homework:
Weekly Practice 1.3 (Due on Friday for even classes. Odd classes should also have this assignment completed by then, but you will be turning it in next Monday). It would be a great idea to attempt all of these problems before Wednesday so you can come in and ask any questions if you need some help. There will be a quiz covering this material on Friday.
Thursday 9/21 and Friday 9/22
Weekly Practice 1.2 (Due today for odd classes and on Tuesday the 26th for even classes ) Come to class prepared for the weekly quiz on Friday(odd) or Tuesday (even).
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?
Tuesday 9/19 and Wednesday 9/20
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 (Remember the answer key is in my room if you get stuck)
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:
We will model effective nuclear charge in class today and spend the second half of 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
Friday 9/15 and Monday 9/18
Weekly Practice Problems 1.1 (Due today for even classes and on Monday the 18th for odd classes ) Come to class prepared for the weekly quiz.

Weekly Practice 1.2 (Remember the answer key is in my room if you get stuck)
Wednesday 9/13 and Thursday 9/14
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.
Remember to finish the Weekly Practice Problems 1.1 before AO tomorrow so you can come in for help if you need to. Also, all isotope numbers should be indicated on the weekly practice 1.1 assignment.
Weekly Practice Problems 1.1 (Due on Friday the 15th for even classes and on Monday the 18th for odd classes ) There will be a quiz covering this material on the due date.
Monday 9/11 and Tuesday 9/12
Proficiency pre-test. Don't worry, these will not be entered into the grade book; it is only to help me keep track of what you learn throughout the year.
We will start our first unit on Atomic Structure. By the end of 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.
More practice with the parts that make up an atom and isotopes Isotopes POGIL

Thursday 9/7 and Friday 9/8
Today we will aim to accomplish a few things:
Orient everyone to the classroom with Mr. Beran's Science Scavenger Hunt. We will use what we find 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.
Wednesday 9/6/17
As homework for this first day, students are to do the following before the next scheduled class period:
Read the Course Syllabus (see below) (a hard copy will not be provided, nor will it be needed). Bring your questions for the next class period.
Print out the last page of the Course Syllabus and return it signed by both you and your parents. This insures that all students are able to access and obtain materials off of the class website and that parents and students understand class expectations.
Print, read, and then sign the Safety Contract (see below) Have your parents sign this contract as well. Signed Safety Contracts are to be returned to class prior to participating in lab activities.
