Electrons and chemical bonding spring 2013 day 3

  1. 1. You Will Need: 1. Pencil, Text Book- Periodic Table, Colored Pencils 2. Ionic & Covalent Bonding 1 pages-2 sides (pgs 7 & 8 of packet) 4. Test #2 Signature and Corrections– Due NOW
  2. 2. Please SCHEDULE: 1. To take Retake Test #2 • 129/185 or lower 2. Starts Thursday of this week 3. Parent Signature and Corrections – due Today.
  3. 3. You will need 100 3 x 5 cards 1. Print out Questions & Answers hyperlinked on Learning Point • Glue, Staple or Tape Questions on the Front and Answers on the back OR • You can write out the questions & answers 2. Due at the beginning of class on Friday 3. Quiz on Friday
  4. 4. Forming Sodium Chloride http://www.youtube.com/watch?v=2mzDwgyk6QMBefore (pg. 233) AfterQuestions: Questions:1)Why does Sodium become an Ion? 1)Why do Sodium and Chlorine bond?2)Is it Positive or Negative? Why? 2)What is the overall charge of the3)Why does Chlorine become an Ion? compound?4)Is it Positive or Negative? Why? 3)Does NaCl have the same characteristics as Na and Cl? 4)What are some unique characteristics of NaCl?
  5. 5. Question AnswerCharacteristics of Covalent bonds • Valance electrons are shared • More often between nonmetal • Low melting and boiling point • Free flowing but can be brittle • Form molecules • Do not have a specific shape - flexibleView Video – Covalent Bonding –hyperlinked on Learning Point. How many types of covalent bonds are shown in thehttp://www.youtube.com/watch?v=1wpDicW_MQQ video clip? ______

  7. 7. http://www.youtube.com/watch?v=ulyopnxjAZ8&feature=relmfuDrawing Lewis Dot Diagram BondsMolecule Illustration Explanation Electron Dot (Color Code each element) 1. What kind of bond does Hydrogen & Oxygen make? 2. How do you know? P=8 N=8 3. Why does one Oxygen bond with two Hydrogen P=1 P=1 atoms? N=0 N=0
  8. 8. http://www.youtube.com/watch?v=7DjsD7Hcd9UHow do we determine the type of • Identify class of elementsbond in a compound? • Same class usually covalent • Opposite class usually ionic • Calculate the electronegativity factorWhat is ELECTRONEGATIVITY? A measure of how much an element wants an electron P=8How do you know the N=8 Look it up (see next slide)electronegativity factor of anelement? P=1 P=1 N=0 N=0What are the determining values for 0-0.4 = Non-polar covalenteach type of bond? .41-2.0 = Polar covalent >2.0 = Ionic
  9. 9. ELECTRONEGATIVITY VALUES 0-0.4 = Non-polar covalent .41-2.0 = Polar covalent >2.0 = Ionichttp://www.tutor-homework.com/Chemistry_Help/electronegativity_table/electronegativity.html
  10. 10. Let’s try a couple:H2O Calculate the electronegativity factor H = 2.2 O = 3.44 3.44 – 2.2 = 1.24 PolarNaCl P=8 Na = .93 Covalent N=8 Cl = 3.16 P=1 P=1 3.16 - .93 = 2.23 Ionic N=0 N=0 0-0.4 = Non-polar covalent .41-2.0 = Polar covalent >2.0 = Ionic
  11. 11. Homework:1) Ionic and Covalent Bonding – Due Tomorrow2) STAR Cards #1-30 – on 3x5 cards – Due Friday at the beginning of class3) Study Cards 1-30 for Quiz on Friday
