  1. USS Nautilus is Commissioned (1954) • Reading for Thursday – Chapter 8 sections 1-4 • Homework 7.1 – Due Thursday 10/2/14 • Chapter 7 #s 1-8 (all), 13-29 (all), 31-39 (all), 41-44 (all) • Homework 7.2 – Due Tuesday 10/7/14 • Chapter 7 #s 45-56 (all), 58, 61, 62, 71, 72, 74 • Quiz #3 next Tuesday

  2. Nomenclature (the words)

  3. Ionic Nomenclature (the words) name to formula Step 1: write the symbol for each ion Step 2: find the least common multiple of the charges Step 3: figure out how many of each ion you need Step 4: write the formula Note: if you need more than one polyatomic ion, you MUST use parenthesis around it!!!

  4. Ionic Nomenclature (the words) formula to name non-VOS cation VOS cation 1) Write the name of the cation 1) Write the name of the cation 1a) Figure out the roman numeral! 2) Write the name of the anion 2) Write the name of the anion 3) The End 3) The End

  5. Ionic Nomenclature (the words) formula to name non-VOS cation VOS cation 1) Write the name of the cation 1) Write the name of the cation 1a) Figure out the roman numeral!

  6. Bi3N5 bismuth (V) (V) nitride Total cation charges + total anion charges = 0 Bi N3- N3- N3- Bi N3- N3- Bi N3- 3 Bi + -15 = 0 Bi = 5 = oxidation state of Bi

  7. NiTeO4 nickel (II) (II) telurate Total cation charges + total anion charges = 0 Ni TeO42- TeO42- Ni + -2 = 0 Ni = 2 = oxidation state of Ni

  8. Co2(CO3)3 cobalt (III) (III) carbonate Total cation charges + total anion charges = 0 CO32- CO32- Co CO32- Co CO32- 2 Co + -6 = 0 Co = 3 = oxidation state of Co

  9. Pb(CrO4)2 lead (IV) (IV) chromate Total cation charges + total anion charges = 0 CrO42- CrO42- Pb CrO42- 1 Pb + -4 = 0 Pb = 4 = oxidation state of Pb

  10. MnO4- Total cation charges + total anion charges = 0 Total atom “A” charges + total atom “B” charges = charge O2- O2- O2- Mn O2- O2- 1 Mn + -8 = -1 Mn = 7 = oxidation state of Mn

  11. Summary of Ionic Nomenclature Rules • Name to formula: • Write the symbol for each ion • Use the LCM of the charges to find the number of each ion needed • Write the formula • no charges should be written in the final formula • use parenthesis if and only if you need more than 1 polyatomic • Formula to name • Write the name of the cation first, then the name of the anion • if and only if cation is VOS, include roman numeral for charge

  12. Name or give the formula for the following: 1) Na2Se 2) lithium nitride 3) SrI2 4) barium sulfide 5) KCl 6) aluminum oxide Did you get it? 1) sodium selenide 2) Li3N 3) strontium iodide 4) BaS 5) potassium chloride 6) Al2O3

  13. More practice on naming: 1) cadmium chlorite 2) titanium (IV) phosphate 3) calcium acetate 4) copper (II) hydride 5) tin (IV) carbonate 6) Al(OH)3 7) AgF 8) Pb(SO3)2 9) Au2Se 10) Ni(BrO)2 1) Cd(ClO2)2 2) Ti3(PO4)4 3) Ca(C2H3O2)2 4) CuH2 5) Sn(CO3)2 6) aluminum hydroxide 7) silver fluoride 8) lead (IV) sulfite 9) gold (I) selenide 10) nickel (II) hypobromite

  14. mercury (I) phosphite (Hg2)3(PO3)2 Ag2CO3 silver carbonate (NH4)3PO4 ammonium phosphate tin (IV) sulfate Sn(SO4)2 iron (II) hydroxide Fe(OH)2 Co2(SO3)3 cobalt (III) sulfite Mn(CrO4)2 manganese (IV) chromate

  15. Nomenclature (the words)

  16. Na Cl

  17. Na Cl

  18. Na+ Cl-

  19. And Now For Something Completely Different… Co valent Compound • Co – together, shared • valent – having valence • compound -- a pure substance composed of two or more elements whose composition is constant

  20. Non-Metals

  21. carbon

  22. carbon 6 protons

  23. carbon

  24. carbon

  25. CH4

  26. Nomenclature (the words) • Molecular Compounds • MUST contain only nonmetals • MUST be neutral (no overall charge)

  27. Molecular Nomenclature (the words) name to formula Step 1: write the symbol for first element and the subscript number given by the prefix HUH?!?!? Step 2: write the symbol for second element and the subscript number given by the second prefix Step 3: The End

  28. Molecular Nomenclature (the words) prefixes monorail, monologue dialogue tricycle, triangle think Tetris!!! pentagon, pentagram 1 – mono 2 – di 3 – tri 4 – tetra 5 – penta

  29. Molecular Nomenclature (the words) prefixes hexagon heptathlon octopus, Octamom umm… looks kinda like nine? decade 6 – hexa 7 – hepta 8 – octa 9 – nona 10 – deca

  30. Molecular Nomenclature (the words) formula to name Step 1: write the prefix and name of first element (the prefix “mono” is optional) Step 2: write the prefix and name of second element (ending of second element MUST be changed to ide) Step 3: The End

  31. Summary of Molecular Nomenclature Rules • Name to formula: • Write the symbol for first element and the number of them • Write the symbol for second element and the number of them • has NOTHING to do with charges • Formula to name • Write the prefix and name of the first element • do NOT change name of element • Write the prefix and name of the second element • change end of second element to “ide”

  32. Nomenclature of Covalent Compounds 1) I3Se7 2) SO4 3) NH3 4) SiO2 5) dinitrogen pentoxide 6) xenon hexafluoride 7) nitrogen trioxide 8) carbon tetrachloride

  48. Acid Nomenclature (the words) name to formula Step 1: write the symbol for the anion Step 2: balance the charge by adding hydrogen(s) in front Step 3: add an (aq) at the end Step 4: The End charge on the anion = # of hydrogens in acid
