  1. Tuesday February 17 Due Today: Silver Alloy lab Objective: Lab challenge Please note, 3 M KOH is a strong base and it will burn. Handle with care. Do not get any on your skin. Where goggles, lab coat, gloves. Homework: Study for Gas Law Retake DQ: see handout Handouts: NA

  2. Block, February 18-23 Due Today: NA Objective: Review Silver Alloy lab calc Lewis Dot Structures • Use the Periodic table to determine the number of valence electrons • Write Lewis electron dot structures for a variety of molecules • Describe the bonds in those structures as single, double or triple bonds • Write and discuss resonance forms where appropriate Homework: Color solutionworksheet Extra credit on website DQ: see handout Handouts: Lewis Dot structure packet

  8. Tuesday, February 24 Due Today: Color worksheet Objective: • Finish Lewis dot packet and hand in • Begin Lewis Dot WS #1 Homework: • Lewis Dot WS #1 • Extra credit – due prior to 3/13 DQ: see handout – put an x through the 4 sets without the correct answer Handouts: lewis Dot worksheet # 1 Reminders: • Retake linearization prior to 2/27 • Retake AP 1st semester cumulative retake prior to 3/6 if you did not score 100% or above- see study guide

  9. Block, February 25-26 Due Today: Lewis Dot worksheet Objective: Valence Shell Electron Pair Repulsion • Utilize Lewis electron dot structures to predict the AXE formula for a variety of molecules and predict the molecular geometry and bond angles • Build 3-D models to visualize the molecular geometry for a variety of molecules • Draw ball and stick models for a variety of molecules Homework: • Extra credit – due prior to 3/13 DQ: see handout Handouts: VSEPR packet; VSEPR Reference Sheet Reminders: • Retake linearization prior to 2/27 • Retake AP 1st semester cumulative retake prior to 3/6 if you did not score 100% or above- see study guide

  10. Friday, February 27 Due Today: NA Objective: • Assign molecules • Discuss color and cation electron configuration ws • Correct Lewis Dot • Finish up Lewis Dot; VSEPR; Homework: • Finish electron configuration ws • Extra credit – due prior to 3/13 DQ: see handout Handouts: Electron configuration ws & model rubric Reminders: • Retake linearization • Retake AP 1st semester cumulative retake prior to 3/6 to be eligible for curve. Otherwise 3/6 in class. • Note, if you did not score 100% or aboveand do not take it prior to 8 am on 3/6, you will be taking it as a test in class on Friday 3/6. • STEM fair – photo release must be on front of board
