Agenda

  • Warm Up

  • Agenda

  • Naming Game - 15

  • Polyatomic Compounds - 20

  • Polyatomic Practice– 45

  • Exit Ticket – 10

    QUIZ TOMORROW AND TEST THURSDAY

    WORKSHEET #3 is HW


Sorting Activity for Nomenclature

  • How can you identify a compound as a molecular compound?

  • How can you identify a compound as an ionic compound?


Molecular or Ionic?


Live Poll!

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


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


List of Polyatomic Ions


List of Polyatomic Ions


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


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


Partner Practice

  • Sodium Chlorate


  • Potassium Hydroxide


  • Calcium Carbonate


  • Aluminum Chromate


Walking around and practicing by finding our pair
