Yesterday, we started ionic compounds. Today, I want you to show me what they look like, both on paper and as a stick figure. I need a legend. White is sodium, red is lithium, or whatever. Show me a) b) c) Depending on what I think of at that time. You should be able to do all three at once, given the ball and stick models. What are the eight polyatomics that you should probably know from memory? Where might you have seen these?
 * Act One (Entry Task)**
 * You are given a set of ball and stick models. Show me what does**
 * Act Two (Anticipatory Set, Modelling, Demonstration)**
 * Important Polyatomic Ions ||
 * Name || Formula ||
 * acetate || C2H3O2- ||
 * carbonate || CO32- ||
 * nitrate || NO3- ||
 * phosphate || PO43- ||
 * sulfate || SO42- ||
 * chlorate || ClO3- ||
 * hydroxide || <span style="font-family: trebuchet ms,arial,helvetica;">OH- ||
 * <span style="font-family: trebuchet ms,arial,helvetica;">ammonium || <span style="font-family: trebuchet ms,arial,helvetica;">NH4+ ||

Ammonium Nitrate (fertilizer) Acetic acid (Hydrogen acetate) Carbonic acid (Hydrogen carbonate) Phosphoric acid (hydrogen phosphate) plus detergents Hydroxides (in many heavy duty cleaners) . . I will give them examples to do on the board that include using polyatomic ions. It is the same as regular balancing of ionic equations. Only thing is, they act as a team. . There will be more practice needed for polyatomic ions.
 * Act Three (Lecture/Notes/Reading)**
 * Act Four (Lecture/Notes/Reading)**


 * Act Five: (Guided Practice)**

I will have a worksheet or questions for them to do.


 * Act Six (Independent Practice/Closure)**

If time permits, we will go over the questions.
