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. Nomenclature Naming Compounds

  6. Naming Binary Ionic Compounds

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

  8. KCl CrO2 CaCl2 Mn2O5 Al2O3 H2S Na2O etc

  9. Name Each: FeCl2 FeCl3

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

  11. 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

  12. Name Each: CaCl2 TiF2 K2O LiF

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

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

  15. BaO AlCl3Cr2S3 SnO2

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

  17. Drill: Name Each: CaO BiCl3Al2S3 TiO2

  18. Review Drill & HW

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

  20. Show Metals & Nonmetals on the Periodic Table.

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

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

  23. Naming Molecules or Covalent Compounds

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

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

  26. Name Each: CO S2O3N2H4 SO3

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

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

  29. Polyatomic Ion

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

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

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

  33. Naming Polyatomic Ions

  34. Learn the polyatomic table on page 54 • Learn how to use the periodic table to determine polyatomic ions

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

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

  37. H2O H3O+1NH3 NH4+1

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

  39. Naming Ternary Compounds

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

  41. Name Each: CaCO3K2SO4

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

  43. Name: Ti(NO3)2CaSO3 MnSO4

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

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

  46. Review Drill & HW

  47. CHM II HW • Review PP 1 – 5 • Work the attached assignment & turn it in tomorrow. • Lab: Thursday

  48. Name the Following: BaSO4 CuNO3 SO2 (NH4)3PO4

  49. Column 7 Dilemma for Polyatomic Ions • There are 2 polyatomic names (-ate & -ite) for each root element. • Polyatomic ions from column 7 have 4 possibilities

  50. 4 examples from Column 7 ClO4-1ClO3-1 ClO2-1 ClO-1
