What’s in a name? You can use your notes! Part I: 1. You have 10 different compounds . Divide them into two different piles of Compounds: Molecular or Ionic 2. Get Ms. Hoffman to check and see if they are in the right piles 3. Once these piles are checked, convert the symbols to names or the names to symbols on the table in the handout.

Example

Polyatomic Ions Not all Ions exist as singularly charged elements. Notes Polyatomic Ions Not all Ions exist as singularly charged elements. Some ions contain more than one element These ions are called polyatomic ions. Contain two or more elements. Polyatomic ions bond with other elements as a group

How do you recognize a Polyatomic Ion? Normal anions end in –ide Exception: Cyanide and Hydroxide are both polyatomic ions Polyatomic ions have more than one capital letter

Am I Polyatomic? Zinc oxide sodium carbonate Nitrogen sulfide Lithium sulfite Magnesium cyanide potassium hydroxide Silver fluoride

Am I Polyatomic? BaSO4 Li2O Fe2 (SO4) 3 Na2CO3 CoBr2 NaCl AlF3

Notes Formula  Name KCN Using your periodic table and Polyatomic Ion chart, break it down into its cation and anion 2. Write the names of each part, then put them together

NaSO3

Al(HCO3)3

LiOH

MgSO3

Name  Formula Magnesium Bromate Notes Name  Formula Magnesium Bromate 1. Separate into ions using your PToE and polyatomic ion chart. 2. Put parentheses around the polyatomic ion. DO NOT TOUCH INSIDE THE PARENTHESES Swap, drop and chop charges
