  1. DO NOW What are you going to do this week to make yourself a better student? Which class do you need to focus on (pick just 1)? Give the name for: NaBr MgCl2 Use Kris Kross to find the formula for these compounds: potassium chloride beryllium oxide

  2. DO NOW REVIEW What are you going to do this week to make yourself a better student? Which class do you need to focus on (pick just 1)? Give the name for: NaBr MgCl2 Use Kris Kross to find the formula for these compounds: potassium chloride beryllium oxide

  3. THIS WEEK Physical Science Chemistry Monday: naming compounds Tuesday: metals and nonmetals/PLAN test Wednesday: review Thursday: review Friday: exam Monday: naming covalent compounds Tuesday: PLAN test Wednesday: single covalent bonds Thursday: double and triple covalent bonds Friday: Quiz

  4. COVALENT BONDS Silent during notes Your grade could go up by 10% this week if you are on the ball. Make 2nd marking period better than first!

  5. COVALENT BONDS Key Point #1: Covalent bonds are between two nonmetals and where electrons are shared. How does that compare to ionic bonds? Ionic bonds are between a metal and a nonmetal and electrons are transferred.

  6. IONIC OR COVALENT? 1 = ionic 2 = covalent KBr

  7. IONIC OR COVALENT? 1 = ionic 2 = covalent NO2

  8. IONIC OR COVALENT? 1 = ionic 2 = covalent HCl

  9. IONIC OR COVALENT? 1 = ionic 2 = covalent BeCl2

  10. Key Point #2: To name covalent bonds: If the first element has more than one atom, give it a prefix. The second element must have a prefix and end in –ide.

  11. 1 – mono- 2 – di- 3 – tri- 4 – tetra- 5 – penta- 6 – hexa- 7 – hepta- 8 – octa- 9 – nona- 10 – deca- Naming Covalent Compounds

  12. PRACTICE! NO3

  13. PRACTICE! C2N6

  14. PRACTICE! CCl4

  15. FLIP IT AND REVERSE IT! Dihydrogen monoxide

  16. FLIP IT AND REVERSE IT! Nitrogen pentafluoride

  17. FLIP IT AND REVERSE IT! Tricarbon disulfide

  18. INDEPENDENT PRACTICE You must remain in your own seat Keep noise level to a minimum and non-science talk out If you have a question, raise your hand. I will not respond to you calling out my name

  19. PRACTICE! Decide if its ionic or covalent – then NAME IT! N3Br P5Cl4 P2O5 K3N BeCl2 N3O6 Decide if its ionic or covalent and then find the formula! silicon dioxide sulfur trioxide manganese (II) phosphide trinitrogenheptachloride nickel (III) sulfide potassium carbonate

  20. EXIT TICKET Name it: SO2 Find the formula: diborontetrabromide
