Presentation Transcript

  1. Nomenclature (A fancy way to say Naming) PO43- phosphate ion C2H3O2- acetate ion

  2. Predicting Charges on Monatomic Ions KNOW THESE !!!! +1 +2 -3 -2 -1 0 C +/- 4 Cd+2

  3. NO3- nitrate ion NO2- nitrite ion Polyatomic Ions

  4. You can make additional polyatomic ions by adding a H+ to the ion! CO3-2 is carbonate HCO3– is hydrogen carbonate H2PO4– is dihydrogen phosphate HSO4– is hydrogen sulfate Polyatomic Ions

  5. Two Families of Compounds: • Ionic Binary (with and without transition metal) Ternary • Molecular

  6. What is an ionic compound? CATION -- Metal (POSITIVELY CHARGED ION) + ANION -- Nonmetal (NEGATIVELY CHARED ION)  COMPOUND Na+ + Cl-  NaCl A neutral compound

  7. Binary Ionic Compounds Two elements (one metal and one nonmetal; without transition metal) Naming: Use name of metal, then put in name of nonmetal with ‘ide’ as the suffix. Ca2+ + 2 F- ---> CaF2 Calcium fluoride

  8. Naming Binary Ionic Compounds Examples: NaCl ZnI2 Al2O3 sodium chloride zinc iodide aluminum oxide

  9. Learning Check Write the correct formula for the compounds containing the following ions: 1. Na+, S2- a) NaS b) Na2S c) NaS2 2. Al3+, Cl- a) AlCl3 b) AlCl c) Al3Cl 3. Mg2+, N3- a) MgN b) Mg2N3 c) Mg3N2

  10. Binary Ionic Compounds Two elements (one metal and one nonmetal; with transition metal) Naming: Use name of metal, then put in name of nonmetal with ‘ide’ as the suffix. **Difference** Must input Roman Numerals Mn2+ + 2 Cl- MnCl2 Manganese (II) Chloride

  11. Transition Metals Elements that can have more than one possible charge MUST have a Roman Numeral to indicate the charge on the individual ion. 1+ or 2+ 2+ or 3+ Cu+,Cu2+ Fe2+, Fe3+ copper(I) ion iron(II) ion copper (II) ion iron(III) ion Transition metals (except Ag, Zn, Cd, and Al) require a Roman Numeral.

  12. Learning Check Complete the names of the following binary compounds with variable metal ions: FeBr2 iron (_____) bromide CuCl copper (_____) chloride SnO2 _______ ( _____ ) __________ Fe2O3 _______ ( _____ ) __________ Hg2S _______ ( _____ ) __________

  13. Ternary Ionic Compounds An ionic compound with a polyatomic ion! Carbonate Sulfate Nitrate Ammonium Acetate Hydroxide

  14. Naming Ternary Compounds Contains at least 3 elements There MUST be at least one polyatomic ion (it helps to circle the ions) Examples: NaNO3Sodium nitrate K2SO4Potassium sulfate Al(HCO3)3Aluminumbicarbonate or Aluminumhydrogen carbonate

  15. Ternary Ionic Nomenclature Sodium Sulfate Na+ and SO4-2 Na2SO4 Iron (III) hydroxide Fe+3 and OH- Fe(OH)3 Ammonium carbonate NH4+ and CO3–2 (NH4)2CO3

  16. Learning Check 1. aluminum nitrate a) AlNO3 b) Al(NO)3 c) Al(NO3)3 2. copper(II) nitrate a) CuNO3 b) Cu(NO3)2 c) Cu2(NO3) 3. Iron (III) hydroxide a) FeOH b) Fe3OH c) Fe(OH)3 4. Tin(IV) hydroxide a) Sn(OH)4 b) Sn(OH)2 c) Sn4(OH)

  17. Questions?

  18. Mixed Practice! Name the following: Na2O CaCO3 PbS2 Sn3N2 Cu3PO4 HgF2

  19. Mixed Up… The Other Way Write the formula: Copper (II) chlorate Calcium nitride Aluminum carbonate Potassium bromide Barium fluoride Cesium hydroxide

  20. Given the name/formula FeCO3 Iron (III) sulfite Na2Cr2O7 Calcium oxide Cu(ClO4)2 Barium carbonate B2Cl4

  26. Questions? Quiz Time! Clear desk except a pencil

  27. Lab - Intro Directions: Add CORRECT solution to each pipet Add 3-5 drops of EACH solution in assigned box Use a toothpick to mix – NOT your pipet RECORD DATA Ionic Solutions Observe when ionic substances are combined

  28. Clean Up Wash off your transparency into sink Toothpicks go into the garbage Rinse out pipets with water and return CLEAN pipets to container Leave pipets and transparency at your station DONE? Work on your homework!

  32. Lab – where did you see products?

  33. Molecular (Covalent) Naming • One more page of Beaker’s notes were found. Your mission is to come up with a set of rules for molecular naming. **Covalent Compounds are formed between a _____________ and a ________________ . ** • Note: There might not be 6 rules. Nonmetal Nonmetal

  34. Molecular Compounds Two Nonmetals CO2 Carbon dioxide BCl3boron trichloride CH4 methane

  35. PREFIX mono- di- tri- tetra- penta- hexa- hepta- octa- nona- deca- NUMBER 1 2 3 4 5 6 7 8 9 10 Molecular Nomenclature Prefixes

  36. Molecular Nomenclature: Examples • CCl4 • N2O • SF6 • carbon tetrachloride • dinitrogen monoxide • sulfur hexafluoride

  37. More Molecular Examples • arsenic trichloride • dinitrogen pentoxide • tetraphosphorus decoxide • AsCl3 • N2O5 • P4O10
