AP/IB Chemistry Summer Assignment AP/IB Chemistry Summer AssignmentWelcome to AP/IB Chemistry! You will quickly notice that things will be different than they were in Chemistry / Honors Chemistry. For one, you must memorize a lot of the information that was given to you on the Chemistry Reference Tables. This assignment will help us with some of the memorization, math skills, and basic topics that you will need so that we can hit the ground running in August.As you progress through this assignment use the following sources for help;I will be using Google Classroom next year and you should join now: joincode = r7mbuzb(Check your school e-mail for an invitation).I will be using Quizlet next year and you should join now: (A link is posted on Google Classroom).I will be using Remind next year to send out due dates / notifications: text @c39d2e?to the number?81010There is a YouTube playlist of Chemistry videos on the topics in the summer assignment. You can access the playlist with the url provided here ( ) or on Google Classroom. Watch as many videos to help you review as you need. You are welcome to watch others and I will be updating and providing additional links on Google Classroom.Read the AP Chemistry Textbook (Chapters 1-3 will be helpful for the summer assignment). I will be sending each of you an online link/join code once I get them. For the practice problems I will post the answer key; however just copying the answers will not help you prepare!! You need to understand how to solve the problems!Email me for help (timothy.miller01@mpls.k12.mn.us) I will check periodically but not daily!Important Dates / Suggested TimelinePlease have joined my Google Classroom, Quizlet, and Remind by June 30th. Have your elements and ions / ion systems / prefixes memorized by July 31st. I will be available for help August 20-23 between 3 and 4 by appointmentStart work on Worksheets 1 & 2 in August – if possible, work with another AP or IB student as there is power in numbers! Worksheets 1 & 2 are due the first day of classThere will be a quiz on the elements on the first day, and a quiz on the polyatomic ions on the second day of class.What will you hand in?Worksheets 1 & 2 (if you need additional space for worksheet 1, you can turn in your own notebook paper, but it must be neat and labeled correctly)Task 1: Memorize the names of the elements and their corresponding symbolsYou need to know elements 1-56, plus Pt, Au, Hg, Pb, Rn, Fr, Ra, U, PuMany of these elements you will already knowMaking flashcards is helpful – a set is available on Quizlet. It’s important to know these as the periodic table you are provided has only the symbols and not the names of the elements.Task 2: Memorize the ionic charges of the basic (monatomic) ionsThink about the valance electrons!Think about the common elements/ions in that group – transition metals can have more than one charge!!!Group 1 ions = +1Group 2 ions = +2Group 15 (5A) ions (N and P) = -3Group 16 (6A) ions (O and S) = -2Group 17 (7A)/ halogens = -1Zn = +2Ag = +1Cu = +1 or +2Fe = +2 or +3Pb = +2 or +4Sn = +2 or +4Task 3: Memorize the names, symbols, and charges of Polyatomic ions & prefixes on the attached Sheet. Below is some more information that you should know in addition to these:Oxyanions – polyatomics containing oxygen, names end in –ate or –ite-ate is used for the most common form-ite is used for the form with the same charge, but one less oxygenExample:2028825546103003NO - = nitrate2028825609602002NO - = nitriteRemember the Per-, -ate, -ite, hypo- system:Per- indicates one more oxygen than the –ate form (think “perfect = overachieving”, ie = more)Hypo- indicates one fewer oxygen than the –ite formExample:2066925546104004ClO - = perchlorate (b/c it has one more O than the –ate form)2066925609603003ClO - = chlorate (b/c it is the most common)2066925609602002ClO - = chlorite (b/c it has one less oxygen than – ate form)2066925609604004ClO - = hypochlorite (b/c it has one less oxygen than the –ite form)F, Cl, Br, I all behave the sameTherefore, if chlorate is ClO3-, the bromate ion is…BrO3-!!!!Simply substitute one halogen for the otherIf you learn the chlorate series, you also automatically know the bromate, iodate, and fluorate seriesHydrogen(s) can be added to ions with a -2 or -3 charge to make a “new ion” i.e. H2PO4 –1 is dihydrogen phosphate (note the – charge increased by 1 for each H+ added)Task 4: Complete Worksheets 1 & 2: DUE ON THE FIRST DAY (attached)POLYATOMIC IONS & PREFIXESOH- = hydroxide ion mono- = 1 CH3COO- (C2H3O2-) = acetate ion di- = 2 HCO3- = bicarbonate (hydrogen carbonate) tri- = 3 NO3- = nitrate ion tetra- = 4 NO2- = nitrite ion pent- = 5 SO42- = sulfate ion hex- = 6 SO32- = sulfite ion hept- = 7 CO32- = carbonate ion oct- = 8 CrO42- = chromate ion non- = 9 Cr2O72- = dichromate ion dec- = 10 PO43- = phosphate ion NH4+ = ammonium ion MnO4- = permanganate ion CN- = cyanide ionBe able to name polyatomic ions using the rules for adding hydrogen to any ion above such as these below:7435858699540044846955869953003HPO -2 HSO -1 638810126365300348653701263653003 HCO -1 Be able to write formulas for polyatomic ions using the rules above such as these below:Bromite ion periodate dihydrogen phosphite ion _______________hydrogen chromate Name: Date: AP/IB Chemistry Summer AssignmentWorksheet #1 – Math SkillsSignificant Figures (Sig Figs)How many sig figs are in the following numbers? a) 0.0450 b) 790 c) 32.10 Solve the following problems.
