Transcript

  • 1. Naming Binary Ionic Compounds Write the names of the following <ul><li>KCl </li></ul><ul><li>Na 3 N </li></ul><ul><li>CrN </li></ul><ul><li>Sr 3 P 2 </li></ul><ul><li>PbO </li></ul><ul><li>PbO 2 </li></ul><ul><li>Na 2 Se </li></ul><ul><li>Potassium chloride </li></ul><ul><li>Sodium nitride </li></ul><ul><li>Chromium (III) nitride </li></ul><ul><li>Strontium phosphide </li></ul><ul><li>Lead (II) oxide / Plumbous oxide </li></ul><ul><li>Lead (IV) oxide / Plumbic oxide </li></ul><ul><li>Sodium Selenate </li></ul>
  • 2. Ternary Ionic Compounds <ul><li>Will have polyatomic ions </li></ul><ul><li>At least three elements </li></ul><ul><li>name the ions </li></ul><ul><li>NaNO 3 </li></ul><ul><li>CaSO 4 </li></ul><ul><li>CuSO 3 </li></ul><ul><li>(NH 4 ) 2 O </li></ul>
  • 3. Ternary Ionic Compounds <ul><li>LiCN </li></ul><ul><li>Fe(OH) 3 </li></ul><ul><li>(NH 4 ) 2 CO 3 </li></ul><ul><li>NiPO 4 </li></ul>
  • 4. Writing Formulas <ul><li>The charges have to add up to zero. </li></ul><ul><li>Get charges on pieces. </li></ul><ul><li>Cations from name of table. </li></ul><ul><li>Anions from table or polyatomic. </li></ul><ul><li>Balance the charges by adding subscripts. </li></ul><ul><li>Put polyatomics in parenthesis. </li></ul>
  • 5. Writing Formulas <ul><li>Write the formula for calcium chloride. </li></ul><ul><li>Calcium is Ca +2 </li></ul><ul><li>Chloride is Cl -1 </li></ul><ul><li>Ca +2 Cl -1 would have a +1 charge. </li></ul><ul><li>Need another Cl -1 </li></ul><ul><li>Ca +2 Cl 2 -1 </li></ul>
  • 6. Write the formulas for these <ul><li>Lithium sulfide </li></ul><ul><li>tin (II) oxide </li></ul><ul><li>tin (IV) oxide </li></ul><ul><li>Magnesium fluoride </li></ul><ul><li>Copper (II) sulfate </li></ul><ul><li>Iron (III) phosphide </li></ul><ul><li>gallium nitrate </li></ul><ul><li>Iron (III) sulfide </li></ul>
  • 7. Write the formulas for these <ul><li>Ammonium chloride </li></ul><ul><li>ammonium sulfide </li></ul><ul><li>barium nitrate </li></ul>
  • 8. Things to look for <ul><li>If cations have ( ), the number is their charge. </li></ul><ul><li>If anions end in -ide they are probably off the periodic table (Monoatomic) </li></ul><ul><li>If anion ends in -ate or -ite it is polyatomic </li></ul>
