Transcript

  • 1. Writing Covalent & Ionic Compounds You have to master this or you cannot do molar mass correctly.
  • 2. Covalent Rules for Naming <ul><li>Covalent naming has nothing to do with ion chart. </li></ul><ul><li>Use the following chart of prefixes for the subscript. </li></ul>Mono = 1 Di = 2 Tri = 3 Tetra = 4 Penta = 5 Hexa = 6 Hepta = 7 Octa = 8 Nona = 9 Deca = 10
  • 3. Name the following. <ul><li>CCl 4 </li></ul><ul><li>NO 2 </li></ul><ul><li>PCl 3 </li></ul><ul><li>CO 2 </li></ul><ul><li>CO </li></ul><ul><li>H 2 O </li></ul><ul><li>N 3 I 7 </li></ul><ul><li>Carbon tetrachloride </li></ul><ul><li>Nitrogen dioxide </li></ul><ul><li>Phosphorus trichloride </li></ul><ul><li>Carbon dioxide </li></ul><ul><li>Carbon monoxide </li></ul><ul><li>Dihydrogen monoxide </li></ul><ul><li>Trinitrogen heptaiodide </li></ul>
  • 4. Now lets try some Ionic Compounds & Naming
  • 5. COMBINE magnesium and nitrogen Mg +2 N -3 Mg 3 N 2 magnesium nitride Flip flop the charges and turn them into subscripts.
  • 6. K +1 SO 4 -2 Remember, in a Polyatomic ion all the atoms act as one! Even the subscripts!!! If they are already there, they stay there! K 2 SO 4 potassium sulfate potassium and sulfate
  • 7. aluminum and sulfate Al +3 SO 4 -2 Al 2 SO 4 3 ( ) aluminum sulfate How do we separate the subscripts so they look separate?
  • 8. Sample problems 1. Ammonium and chlorine 2. Aluminum and selenate 3. Lead II and bicarbonate 4. Mercury I and phosphate
  • 9. answers 1. NH 4 Cl Ammonium chloride 2. Al 2 (SeO 4 ) 3 Aluminum selenate 3. Pb(HCO 3 ) 2 Lead II bicarbonate 4. (Hg 2 ) 3 (PO 4 ) 2 Mercury I phosphate
