Catalyst – October 1.1x20, 2009Please take HW out. Hold onto your element. • Show the IONIZATION of an Aluminum atom. (Write one equation) • Using Kriss Kross, write the formulas for the following: a) Ga O b) 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! • What has a higher 4th ionization energy? • Nitrogen or Fluorine? • What has a higher 2nd 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!) • Na1+ F1- • Al3+ (NO3)1- • (NH4)1+ Cl1- • 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!) • Cu(II) NO3 • Mg Se • SO4 B • Ca Br
What do you see? Copy the table into your notes and fill in the question marks with what you think is correct.
