Lewis S. Mills High School
AP Chemistry Information and Summer Assignment 2014-2015
Mrs. Rosenfield
rosenfieldk@region10ct.org
AP Chemistry is a college-level course with a lot of material that must be learned before the AP
examination in May. This requires spending most of your time learning new material or going into topics
covered in first-year chemistry in more depth. There will not be time to re-teach a lot of basic concepts.
Because this is a second-year chemistry course, all students will be expected to review and understand
certain fundamentals from first-year chemistry that are needed as a foundation for more advanced topics.
Some of this is pure memorization and some requires an understanding of basic chemical principles. For
example you must memorize the symbols of common elements, the formulas and charges of common
monatomic and polyatomic ions, and be able to determine correct formulas and names of compounds.
You are expected to master the material in the first three chapters of the textbook (Chemistry the
Central Science, 10th edition by Brown, LeMay, and Bursten) before the first day of class. Most, if not
all, of this was covered in your first chemistry course.

This will give you a good idea of what to expect in the course. The timing of the course is similar
to a first year college chemistry course. You should recognize that this will be a challenging and, I hope,
exciting and enjoyable experience, but one that will require a lot of work. You need to be committed to
spending the amount of time to succeed in this course before beginning the year.
The following assignment is to be handed in on the first day of class. It will be graded, and
there will be a test on the material the first week of school. You may either handwrite or type the
answers to the problems but make sure to show calculations to receive credit for completing the
assignment. Feel free to email me at rosenfieldk@region10ct.org if you have any questions about the
assignment.
There will be a quiz on the first day of class on the material that you are supposed to memorize in
Table 1.5 Metric Prefixes, Table 2.3 Names of Some Groups in the Periodic Table, Figure 2.19 Diatomic
molecules, Table 2.4 Common Cations, Table 2.5 Common Anions and Table 2.6 Prefixes, and the list of
ions attached.

Read Chapter 1
o Key terms and concepts to understand:
 classification of matter (mixtures, substances, elements, compounds)
 physical properties vs. chemical properties
 use of units in conversions and dimensional analysis
 precision and accuracy
 significant figures in measurements and calculations
o Do problems pgs. 31-33 # 3, 4, 7, 18, 22, 24, 28, 30, 32, 42, 56, 61.
o MEMORIZE Table 1.5 Metric Prefixes (I don’t want anyone asking me how many
milliliters are in a liter, or how many grams are in a kilogram.)

Read Chapter 2
o Key terms and concepts to understand
 atomic structure and properties of electrons, protons and neutrons
 atomic number, mass number, isotopes, weighted average atomic mass
 groups, periods, metals, nonmetals, metalloids
 molecular formula, empirical formula
 formation of ions, charges on common ions
 ionic vs. molecular compounds
 names and formulas of ionic and molecular compounds
o Do problems pgs. 70-75 # 1, 4, 18, 20, 24, 30, 36, 42, 48, 52, 54, 56, 73 AND complete
the attached worksheet.
o MEMORIZE Table 2.3 Names of Some Groups in the Periodic Table, Figure 2.19
Diatomic molecules, Table 2.4 Common Cations, Table 2.5 Common Anions and Table
2.6 Prefixes, and the list of the common ions found on the AP exam that is attached to this
handout. These are essential prerequisites to being able to write correct names and
formulas of chemical compounds. You will be quizzed on these the FIRST day of class.

Read Chapter 3
o Key terms and concepts to understand
 balanced chemical equations
 Avogadro’s number and the mole
 conversions between mass, moles and number of particles
 empirical and molecular formulas
 percent composition
 limiting reactant
 calculations relating amounts of reactants and products
 theoretical, actual and percent yield
o Do problems pgs. 110-116 # 5, 6, 12, 14, 16, 26, 34, 38, 42, 44, 48, 50, 54, 58, 60, 67, 68,
73, 79, 89.

Common ions found on the AP exam
Mastering this list of ions names, formulae, and charges, is essential to success in AP Chemistry. You are expected to know all
of these ions on the first day of class, when I will give you a
quiz on them. You will always be allowed a periodic table, which makes identifying the ions on the left “automatic.” I will
have Tips for Learning the Ions on my wiki page for you and I will be placing a link to study cards using Quizlet
(unfortunately, I cannot sub- and superscript with Quizlet so you will have to allow for that when learning them).
