  1. Naming Ionic Compounds Chemical Bonding

  2. Lewis Structures

  3. How to write a formulawith transition metals • When a Transition metal is involved in the bond, you must identify which form of the atom is bonding. • These atoms can have different oxidation numbers. • Look for the Roman Numeral in the name when writing the formula. The Roman numeral is the oxidation number of the transition metal. Copper (II) Fluoride Cu+2 2F -1 CuF2

  4. Writing Formula Practice Copper (II) Fluoride Cu+2 2F -1 CuF2

  5. Writing Names Practice Copper (II) Fluoride Cu+2 2F -1 CuF2

  6. How to write a formulawith polyatomic ions • If you have a compound with a polyatomic ion, the name will have a different ending using either (-ate) or (-ite) • Use your polyatomic ions chart to determine the ion • When writing formulas, keep these ions in parentheses if there is more than one polyatomic

  7. Writing Formula Practice Sodium Nitrate Na+1 NO3 -1 NaNO3

  8. How to write a namewith polyatomic ions • Look for more than two elements. That’s means a Polyatomic is present. • Match up the polyatomics and write the correct names and ending straight from the chart.

  9. Writing Names Practice Sodium Nitrate Na+1 NO3 -1 NaNO3
