  1. 11/12/12 Veteran's Day NO SCHOOL

  2. 11/13/2012 Standards: 2 Objectives: a. Be able to figure relative lattice energies b. Be able to put + & - ions together to make molecular formulas for ionic compounds c. Be able to name ionic compounds with Type 2 metals (can have more than one charge). DO NOW: 1. Slap-it - using 10 ions - (see next page) - Mem Ions 2 this Fri. HOMEWORK: 1. ChemThink.com - Ionic Formulas - Tutorial (5 pts), Questions (10 pts) Std 2 due Wed 11/14 2. Ch 8 Assess, p. 236 47-59 (don't do 56 or 58) - copy q's, give best answers 3. Help Sheet - Quiz 2.2 coming Thurs. ========================================================= BASKET: Journal 11/9 1. Write Chemical Formulas & Name - Practice (5 pts) Std 2 New Stamp Sheets front side 13-15 back side 16-18

  3. Coming Friday 11/16

  4. Lattice Energies are always given as negative numbers SIZE Smaller ion ===> more lattice energy Larger ion ===> less lattice energy CHARGE Larger (+ or -) ===> more lattice energy INDIRECT DIRECT

  5. Metals in Ionic Cmpds w more than 1 possible charge anion (-) charge x its subscript ----------------------------------------------- cation (+) subscript Roman numeral after metal cation (+) =

  6. 11/14/2012 Standards: 2 (Chemical Bonding) Objectives: a. Be able to name ionic compounds, binary & poly anions. b. Be prepared for tomorrow's Quiz 2.3 (Ch 8 & all prior chapters) DO NOW: 1. Name these molecules: FeCl3 SnSO4 SnBr V(CO3)2 VCl5 VPO4 V(C2H3O2)2 2. Last night's homework problems. HOMEWORK: 1. Quiz 2.3 On-Line Pract. Quiz. DO NOT PRINT Copy or summarize q's, give correct ans, and page # with reason for your ans. Density problem requires GIVEN, FIND, & CALC (10 pts) =================================================== BASKET: Journal 11/13 1. Ch 8 Assess, p. 236 47-59 (leave out 56 & 58) (10 pts) Std 2 AT YOUR DESK: 1. Help Sheet (5 pts) Std MISC RESPONDERS

  7. Notebooks will be collected starting tomorrow (Thurs) Thurs 11/15 Per 1 & 2 Friday 11/16 Per 3 Mon 11/19 Per 5 & 6 Look for link for RUBRIC on Home Page of Website in ANNOUNCEMENTS

ChemThink.com - Covalent Bonding - Tutorial (5 pts) and Questions (10 pts) - Due Monday 11/19 by midnight. ============================================================ BASKET: Practice Quiz 2.3 (10 pts) Std 2 Remember - Mem. Ions 2 coming tomorrow (11 ions - ammonium ---> chlorite

  12. Density problems: Back of scantron Show Given & Find Show calculations (if the find is density, just show one fraction Circle answer

  13. Put everything in 5 stacks FIRST help sheet scratch paper THE FOLLOWING ARE IN ORDER - SMALLEST # ON TOP scantron periodic chart quiz

  14. 11/16/2012 Standards: 2 (Chemical Bonds) Objectives: a. Allow students to correct any problem in grading afftecting 15 wk grade b. check for understanding w Mem. Ions 2 (11 questions, 11 points) c. Be able to write Lewis Structures for COVALENT MOLECULES DO NOW: 1. Slap-it with the ions you will be quizzed on after the HW is stamped. HOMEWORK: 1. Make 5 more cards for Memorize Ions - chlorate ion, perchlorate ion, hydrochloric acid, sulfuric acid, phosphoric acid. 2. Ch 9.1 p. 244 pp's 1-5 (5 pts) Std 2 3. ChemThink.com - Covalent Bonding - Tutorial & Q's is Due Mon at midnight. =========================================================== Journal: 11/14 (DAY before quiz) BASKET: 1. SN Ch 9.1 p. 107-110 (5 pts) Std 2 RESPONDER QUIZ MON. (5 PTS) CFA for Chem Dept on Standard 1

  15. RESPONDER QUIZ MON. (5 PTS) CFA for Chem Dept on Standard 1 How to prepare: 1. Go to "Standard Stuff" > "California St. Standards" 2. Click on "Expand Categories" on the right of the screen, just under the calendar 3. Every assignment given to you for this standard is show by "Strand". Peruse each strand's: State Standard Students Will Be Able To In Class Assignments Homework Labs Lecture Notes Look for anything that you don't understand and use Homework, Lecture Notes, & Tutorials to get a better understanding.

  16. ChemThink.com Covalent Bonding Tutorial as intro to COVALENT BONDING STD 2 http://youtu.be/ZYrzHU7EpNM

  17. Rules for drawing Lewis Structures of covalently bonded molecules 1. All atoms must have 8 of the available valence electrons (octet rule) 2. At the end, check to see that all of the valence electrons have been used NO MORE, NO LESS
