Presentation Transcript

  1. Drill: Determine the atomic mass of the following element that exist as: • 10.00 % Px-399 • 65.00 % Px-400 • 20.00 % Px-401 • 5.00 % Px-402

  2. Review Drill,Grade HW & Collect Both

  3. CHM II HW • Review PP 5 • No written homework over the holiday weekend

  4. CHM II HW • Review PP 5 • Work the attached assignment & turn it in tomorrow.

  5. Are there any questions on previous material?

  6. Nomenclature Naming Compounds

  7. Naming Binary Ionic Compounds

  8. Name positive element first with its normal name • Name negative element last & change its ending to -ide

  9. KCl CrO2 CaCl2 Mn2O5 Al2O3 H2S Na2O etc

  10. Name Each: FeCl2 FeCl3

  11. If the Positive element is not from columns I or II • its ox # must be determined and written in roman numerals

  12. Determining the Charge • Add up the oxidation numbers of all the negative elements • The positive portion must balance out the negative portion • Divide the positive portion by the metal subscript

  13. Name Each: CaCl2 TiF2 K2O LiF

  14. Deriving Formulas • Write the symbol for each element • Determine each element’s charge & apply subscripts to balance charge

  15. Derive Formulas • Magnesium chloride • Lead(II)sulfide • Iron(III)carbide

  16. BaO AlCl3Cr2S3 SnO2

  17. Derive Formulas • Potassium chloride • Chromium(III)phosphide • Lead(II)iodide • Tungsten(IV)arsenide

  18. Drill: Name Each: CaO BiCl3Al2S3 TiO2

  19. Review & Collect Drill & HW

  20. CHM II HW • Review PP 5 • Complete the attached assignment & turn it in tomorrow.

  21. Are there any questions on previous material?

  22. Show Metals & Nonmetals on the Periodic Table.

  23. Ionic Compounds • Large EN difference • Metals bound to nonmetals

  24. Covalent Compounds • Small EN difference • Nonmetals bound to each other

  25. Metallic Compounds • Substances that contain metals only

  26. Naming Molecules or Covalent Compounds

  27. Same rules as ionic compounds except: • use geometric prefixes to determine the # of each atom

  28. Geometric Prefixes 1-mono 5-penta 2-di 6-hexa 3-tri 7-hepta 4-tetra etc

  29. Name Each: CO S2O3N2H4 SO3

  30. Write formulas for: • Sodium sulfide • Lead (II) iodide • Diphosphorus pentoxide

  31. Write formulas for: • Chromium(III) oxide • Aluminum carbide

  32. Polyatomic Ion

  33. A group of atoms chemically combined that together has a charge

  34. Most are oxoanions • PO4-3 SO4-2 • A root element bound to oxygen

  35. Drill: Name each CuCl2 KBr PCl5 MgO Mn2O7 S2O3

  36. Naming Polyatomic Ions

  37. Learn the polyatomic table on the internet • Learn how to use the periodic table to determine polyatomic ions

  38. Name the root element • Change the ending to -ate • PO4-3 = phosphate • Some are unusual

  39. CN-1 OH-1 C2H3O2-1C2O4-2

  40. H2O H3O+1NH3 NH4+1

  41. Polyatomic Ion Endings • Maximum O = -ate • 1 less than max O = -ite • SO4-2 = sulfate • SO3-2 = sulfite

  42. Naming Ternary Compounds

  43. Follow ionic rules for naming the compound • Name the polyatomic ion as the positive or negative portion

  44. Name Each: CaCO3K2SO4

  45. Write Formulas For: • Lead (II) nitrate • Aluminum sulfate • Potassium chromate • Ammonium phosphite

  46. Name: Ti(NO3)2CaSO3 MnSO4

  47. Write Formulas For: • Magnesium nitrate • Aluminum phosphate • Potassium nitrite • Ammonium chloride

  48. Drill: Name: Pb(NO3)2MgSO3 S2O4

  49. Review Drill & HW
