6. Live Poll!

7. 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.

9. 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
