  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 NO2 CaCl2 P2O5 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. Name Each: CaCl2 CaS K2O LiF

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

  9. 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

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

  11. Naming Molecules or Covalent Compounds

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

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

  14. Name Each: CO S2O3N2H4 SO3

  15. Drill: Name Each: CaO P2O5Al2S3 SO2

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

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

  18. Polyatomic Ion

  19. A group of atoms chemically combined that together have a charge

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

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

  22. Naming Polyatomic Ions

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

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

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

  26. H2O H3O+1NH3 NH4+1

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

  28. Naming Ternary Compounds

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

  30. Name Each: CaCO3K2SO4

  31. Drill: Name: Pb(NO3)2MgSO3
