Ionic Nomenclature & Compounds

  1. 1. Ionic Nomenclature Komperda
  2. 2. Rules for Formulas <ul><li>All atoms must achieve stable electron configuration (full valence) </li></ul><ul><li>The formula must be electrically neutral </li></ul><ul><ul><li>The sum of the positive and negative charges must equal zero </li></ul></ul>
  3. 4. How do we name our formulas? <ul><li>Name the cation first, then the anion </li></ul><ul><li>Do not include the numbers in the name </li></ul><ul><li>Example: </li></ul><ul><li>BaCl 2 = Barium Chloride </li></ul>
  4. 5. Transition Metals <ul><li>Form more than one type of cation </li></ul><ul><li>Must use Roman Numerals to distinguish which cation is in the formula </li></ul><ul><li>Roman Numerals are ONLY used in the NAME, not in the formula </li></ul><ul><li>The Roman Numeral stands for the charge on the cation, NOT THE SUBSCRIPT in the formula </li></ul>
  5. 7. Formula vs. Name <ul><li>FeN = Iron (III) Nitride </li></ul><ul><li>Cu 2 O = Copper (I) Oxide </li></ul><ul><li>SnO = Tin (II) Oxide </li></ul><ul><li>SnO 2 = Tin (IV) Oxide </li></ul>
  6. 8. How do I figure out what to name it?
  7. 9. What do Ionic Compounds look like? <ul><li>Ionic compounds form salts </li></ul><ul><li>Think of table salt </li></ul><ul><li>Cations are smaller than the parent atom </li></ul><ul><li>Anions are bigger than the parent atom </li></ul><ul><li>The compounds formed become tightly packed spheres of atoms </li></ul>
  8. 10. Sizes of Ions
  9. 12. The Positions of the Centers of the atoms form a matrix
  10. 13. Review <ul><li>Simple Binary Ionic Compounds use the simple names of the ions </li></ul><ul><li>Transition Metals with more than one charge use Roman Numerals in the name, not in the formula </li></ul><ul><li>Names and formulas are cation first, then the name of the anion </li></ul>
