Welcome to AP Chem! This course is designed to challenge you to think critically, solve complex problems, and explore the fascinating world of chemistry at a deeper level. AP Chem requires curiosity, persistence, and hard work, but you'll be rewarded by growing as a scientist and thinker. I am excited to work with you this year and watch you succeed!
2026 -2027 First Unit Jumpstart! None of the "assignments" listed below are required, and they will not be graded. However, if you want to do some review before we start the year (or if you're just really missing Chemistry) here are some activities/worksheets to help you out. Feel free to email me with questions.
The tentative schedule for our first unit is as follows:
8/10: Classroom Expectations
8/11: Lab Safety Stations
8/12: Sig Figs
8/13: Temperature Scales
8/14: Nomenclature
8/17: Molar mass and moles
8/19: Unit quiz!
Review Assignment #1: Memorization and Preparation of Notecards
Good news: You don't really need to have this information memorized for the current AP Chem test. You may need it in university classes. However, you'll find that you can work faster and easier if you're familiar with the periodic table, and memorizing this info certainly won't hurt. It may even make you look cool.
Go to AP® Chemistry Exam Reference Information and print the AP Periodic Table. This is the same periodic table we will use in AP Chemistry. Notes that the names of the elements are not given, and oxidation states are not included.
Make notecards of the following elements by placing the element symbol on one side and the name and oxidation states (if given below) on the other side. You should have a periodic table in front of you when trying to recite the charges as the location of elements often gives away the oxidation state. (For example, group 1 metals are always and only a +1.) Elements without an oxidation state listed below only need to be memorized for the symbol/name.
Common elements and oxidation states:
H He Li (+1) Be B C (-4,+2,+4) N (-3 to +5 wow!) O (-2, -1, +2) F (-1) Ne Na (+1) Mg (+2) Al (+3) Si P S Cl Ar K (+1) Ca (+2) Sc Ti V Cr Mn Fe (+2, +3) Co Ni (+2, +3) Cu (+1, +2) Zn (+2) As Se Br Kr Sr Ag (+1) Cd (+2) Sn (+2, +4) Sb Te I Xe Ba (+2) W Pt Au Hg (+1, +2) Pb (+2, +4) Bi Rn Ra U Pu
Go to Reference Tables for Physical Setting/Chemistry 2011. Make notecards for the information in the following tables:
Table E: Name on one side, formula and charge on the other side.
Table F: Ions on one side, soluble or not with exceptions on the other side.
Table K: Common Acids - Name on one side for each, formula on the other side for each.
Table L: Common Bases - Name on one side for each, formula on the other side for each.
Diatomic Elements (I would put these on your AP periodic table as well): Cl2, Br2, F2, O2, H2, N2, I2

Review Assignment #5 - Balancing Chemical Reactions and Determining Types
https://docs.google.com/document/d/1WP61mCyXdBpC6jp-DpmP-Vyphx-t88emk9wLznmTB04/edit?usp=sharing
Directions: Balance each chemical reaction using whole numbers only. If a line is left blank it will be assumed that it is a one. It is best if you keep the polyatomic ion together for the purpose of balancing the equation. Also, identify the type of reaction as Synthesis, Decomposition, Single Replacement, Double Replacement, Organic Combustion or OTHER.
