Catalyst – October 1.1x20, 2009 Please take HW out. Hold onto your element. 1. Show the IONIZATION of an Aluminum atom. (Write one equation) 2. Using Kriss Kross, write the formulas for the following: a) Ga O b) Na CO 3 c) Cl Mg
Today’s Agenda Catalyst More Ionic Review Practice Naming Ionic Compounds Unit 3 Tracking/Work Time Exit Question HOMEWORK: Personals Ad Project
Ionization Energy Review Try these on your own! 1. What has a higher 4 th ionization energy? Nitrogen or Fluorine? 2. What has a higher 2 nd ionization energy? Aluminum or Silicon?
Today’s Objectives SWBAT write formulas for ionic compounds. SWBAT name ionic compounds.
Ionic Formula Practice Write formulas for the compounds that will form from the following ions. (Just use Kriss Kross!) 1. Na 1+ F 1- 2. Al 3+ (NO 3 ) 1- 3. (NH 4 ) 1+ Cl 1- 4. Be 2+ O 2-
Ionic Formula Practice Write formulas for the compounds that will form from the following elements and polyatomics. Now, YOU have to create the ion! (And use Kriss Kross!) 1. Cu(II) NO 3 2. Mg Se 3. SO 4 B 4. Ca Br
What do you see? Copy the table into your notes and fill in the question marks with what you think is correct. Formula for Ionic Compound Name for Ionic Compound NaClSodium chloride CaCl 2 Calcium chloride KBrPotassium bromide MgF 2 ??? NaBr???
Naming Ionic Compounds KEY POINT: Rules of naming… 1)Write name of first element (metal). 2)Second element ends in -ide. 3)Ignore subscripts!
Naming Ionic Compounds Draw a mental line between the ions. Na + Cl -
Naming Ionic Compounds Binary Ionic Compound – an ionic compound composed of two elements
