AP Chemistry 2011-2012
The following assignment needs to be completed by the first day of school.
It will be collected and graded. Keep something in mind, this is your first
assignment for AP Chemistry, it doesn’t look too good when you show up for
school and, “left it at home,” or “didn’t have time to finish it.”
Plan for Lab Orientation at Thomas More College on Friday, August 19 from
3:00 till approximately 5:00.
You should be able to find any information you need in your notes from last year and in your AP chemistry
book. This packet contains information which is review of material that has already been covered in Honors
Chemistry- we work hard to provide you a strong foundation so that we don’t have to cover the basics over
again. AP chemistry is an intense course by nature; it requires a great deal of maturity on your part and time
outside of class, on your own, working through the material. We want to have as much time as possible for
new material; therefore, it’s important that we move through “review” material quickly.
You may work together this summer on the assignment (consider it training in forming good study groups),
but be aware- YOU are responsible for this material. There will be a test very soon after we come back to
school which will cover chapter 1- soon to follow those, will be chapters 2 and 3. Keep in mind- they are
review!!! The summer work isn’t too bad but you may have to look things up in your book- don’t be afraid to
search for the answer! Just because you don’t know what to do right away doesn’t mean you can’t look it up
and figure it out!
Two last things- my notes which cover chapters 1, 2, and 3 will appear on the internet at my website; you can
refer to these or the notes from last year should you need any help. If you lose your summer work packet,
there will be additional packets available in my mailbox at the school and posted on the schools webpage!
Have a fun and safe summer!!
*Note: It’s best to wait until towards the end of the summer before attempting these problems- if you do
them too early in the summer, the point of refreshing your memory will be lost!

Writing Formulas and Naming Compounds
Writing formulas and naming compounds can be confusing because there are different types of compounds that
follow different rules. Additionally, some compounds (H2O, NH3, CH4, etc.) simply have common names that
must be memorized.
The two types of compounds we will focus on first are ionic compounds (formed from positive and negative
ions) and binary nonmetal compounds (molecular compounds). Later we will add acids. So… you must
recognize the type of compound before you try to name it. [Note: + ion = “cation” and – ion = “anion”.]
Ionic Binary Nonmetal
+ ion before – ion usually the less electronegative atom is first
ex: NaCl (NH4)2SO4 Al2S3 ex: CO CO2 N2O
Name of cation + name of anion Indicate the number (mono, di, tri, and kind of atoms.
First element is simply name of element. Second
sodium chloride element name ends with “ide”
