summer assignment instructions and ions

AP Chemistry Summer Assignment

The summer assignment for AP Chemistry consists of three chapter review assignments from your AP Textbook (attached).  You are not to write in these books.  You are free to take the diagnostic and practice tests in the book and on the CD that is included at any time.  You are assigned Diagnostic Test 1 this summer to get a taste of what is in store for you.  We will be doing many of them throughout the year, but what work you put in to studying the material is what will determine your ultimate score on the AP Exam.  There are homework assignments for each chapter that you will need to turn in to my mailbox over the summer at school or mail them to me (3540 Public Well Street) or school (309 S. Main Street) postmarked by the due date  and write questions on your homework so I can see it and get back with you if needed.  My cell is 217-264-0467 and my e-mail is:  I will ask for your cell to text you reminders and communicate with you throughout the year.   You will also need to master the formulas, charges, and names of the attached common ions.  On quizzes, you will need to:

write the names of these ions when given the formula and charge
write the formula and charge when given the names

I have included several resources in this packet. First, there is a list of the ions that you must know for the course. This list also has, on the back, some suggestions for making the process of memorization easier. For instance, many of you will remember that most of the monatomic ions have charges that are directly related to their placement on the periodic table. Main groups I, II, III, and IV elements usually form ions of +1, +2, +3, and +4 respectively.  Main groups V, VI, and VII usually from -3, -2, and -1 ions respectively.  Main group 8 does not usually form ions and the transition elements usually form a +2 ion unless otherwise given a Roman Numeral or –ous/-ic ending to help you out.  There are naming patterns that greatly simplify the learning of the polyatomic ions as well.  You will be quizzed on these ions the first week of school and throughout the year on dailies (daily quizzies) for a grade.

Also included is a copy of the periodic table used in AP Chemistry.  The AP table is the same that the College Board allows you to use on the AP Chemistry test.  Notice that it has the symbols of the elements but not the written names. Therefore, you must also recognize all the elements by symbol and match to name.  This will be another quiz.

I have included a sheet of flashcards for the polyatomic ions to help you learn. I strongly suggest that you cut them out and begin memorizing them immediately.  Do not let the fact that there are no flashcards for monatomic ions suggest to you that the monatomic ions are not important. They are every bit as important as the polyatomic ions. If you have trouble identifying the charge of monatomic ions (or the naming system) then I suggest that you make yourself some flashcards for those as well.  Chloride is Cl- for example and aluminum is Al +3.

Doubtless, there will be some students who are losers and will not get there summer work in on time.  The grade will suffer and go down 10% each day that it is late.  All research on human memory shows us that frequent, short periods of study, spread over long periods of time will produce much greater retention than long periods of study of a short period of time. There are a series of bozeman education videos that you will be required to watch as well.
