Transcripts - Naming binary compounds part ii

  • 1. Naming Binary Compounds Part II The Stock System
  • 2. ObjectivesName simple binary compounds using theirformulae.Given the name, write the formula of a simplebinary compounds
  • 3. The Stock SystemThe Stock System is used when the cation or thefirst part of the compound has more than onepossible charge.The charge of the cation/metal is denoted by aRoman Numeral.
  • 4. Roman Numerals1=I2 = II3 = III4 = IV5=V6 = VI7 = VII
  • 5. Special Case: Hg +1Hg+1 is never by itself.When you see it in a formula it will look like Hg2and have a +2 chargeExample: Hg2Cl2 is mercury(I) chlorideHowever, Hg+2 is mercury(II)Example HgCl2 is mercury(II) chloride
  • 6. ExamplesIron has 2 possible charges Fe+2 & Fe+3They would be Fe (II) or Fe (III)Ions/metals that only have one charge there is noreason to use the Roman Numerals
  • 7. ExamplesFe2O3 and FeOIn Fe2O3 the Iron has a +3 charge so the namewould be: Iron (III) OxideIn FeO the Iron has a +2 charge so the namewould be: Iron (II) Oxide
  • 8. Try It Your SelfStep I: Determine the charge on the metalsusing the non metal part (ex. O and Cl)Step II: Write the correct name.Here are your problems: CuO and CuClNow pause the video and try them.
