  1. Nomenclature Naming Compounds

  2. Naming Binary Ionic Compounds

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

  4. KCl CrO2 CaCl2 Mn2O5 Al2O3 H2S Na2O etc

  5. Name Each: FeCl2 FeCl3

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

  7. 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

  8. Name Each: CaCl2 TiF2 K2O LiF

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

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

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

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

  13. Name Each: CO S2O3N2H4 SO3

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

  15. Write formulas for: • Chromium(III) oxide • Aluminum carbide • Dibromine heptoxide

  16. Polyatomic Ion

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

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

  19. Naming Polyatomic Ions

  20. Google Polyatomic Ion Chart at Home & Learn the Chart

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

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

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

  24. H2O H3O+1NH3 NH4+1

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

  26. Naming Ternary Compounds

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

  28. Name Each: CaCO3K2SO4

  29. Name: Ti(NO3)2CaSO3 MnSO4

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

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

  32. 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

  33. 4 examples from Column 7 ClO4-1ClO3-1 ClO2-1 ClO-1

  34. 4 examples from Column 7 ClO4-1 perchlorateClO3-1 chlorateClO2-1 chlorite ClO-1 hypochlorite

  35. Also true for others IO4-1 periodateIO3-1 iodateIO2-1 ioditeIO-1 hypoiodite

  36. Naming Acids

  37. ___ ide ions become: • hydro ___ ic acids • ___ ate ions become: • ___ ic acids • ___ ite ions become: • ___ ous acids

  38. Name or Give Formulas For: • HBr(aq) H2SO4(aq) • NaNO3 (NH4)3PO3 • Phosphoric acid • Nitric acid • Chloric acid
