Catalyst – October 1.1x20, 2009Please 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 Ob) Na CO3
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 ReviewTry these on your own!
1. What has a higher 4th ionization energy?
Nitrogen or Fluorine?2. What has a higher 2nd
ionization energy? Aluminum or Silicon?
GEE Test Practice:
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. Na1+ F1-
2. Al3+ (NO3)1-
3. (NH4)1+ Cl1-
4. Be2+ O2-
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) NO3
2. Mg Se3. SO4 B
4. Ca Br

Naming Ionic CompoundsKEY POINT: Rules of
naming…1)Write name of first element (metal).
2)Second element ends in -ide.
3)Ignore subscripts!

Ionic Cheat Sheet!
Naming Ionic CompoundsDo not lose
this…you will need it the rest of your life (in my class).
Naming Ionic Compounds
The way you use it…
Naming Ionic Compounds
1) Look up the ions on the cheat sheet
and write the words next to
them.
