** Ionic Formulas From Names ** **<---Previous Assignment - Next Assignment--->media type="custom" key="20561230"**


 * __Time Length__ **
 * **2 Days**
 * __Instructions__ **
 * **On your own paper**, complete the worksheet below (you do not need to write down the question unless you want to)
 * __In your head__, Identify what group of ion the cation (first name) and anion (last name) are in so you can find the charge..
 * (Either Representative, Transition, or Polyatomic ions.)
 * Write down their symbols and charges (write this down to show your work)
 * Use the bonding rules from the notes on 11-1 to write the formula.
 * ** Hint: ** for Identifying anions(last name): if the anion(last name) ends in "ide" it probably has been changed
 * Oxide means Oxygen, Hydride means Hydrogen, etc.
 * However, there are a few polyatomic ions whose name ends in "ide"
 * Peroxide and Hydroxide are examples.
 * __Worksheet__ **

You will need the following document for charges of Polyatomic Ions.
