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 Compounds

What do you see? Copy the table into your notes and fill in the question marks with what you think is correct.

Naming Ionic CompoundsKEY POINT: Rules of

naming…1)Write name of first element (metal).

2)Second element ends in -ide.

3)Ignore subscripts!


Draw a mental line between the

ions.Na+ Cl-


Binary Ionic Compound – an ionic compound

composed of two elements


ZnO

Naming Ionic CompoundsKEY POINT: Rules of

naming…1)Write name of first element (metal).

2)Second element ends in -ide.

ZnO


ZnO

Zinc Oxide


CaCl2


CaCl2

Calcium Chloride


Al2O3


Al2O3

Aluminum Oxide


Ternary Ionic Compound – an ionic compound with more than

2 elements


Ionic Cheat Sheet!

Naming Ionic CompoundsDo not lose

this…you will need it the rest of your life (in my class).


The way you use it…


1) Look up the ions on the cheat sheet

and write the words next to

them.


BaCO3


BaCO3

Barium


If the first element is +2, where should we find the second?

(Remember, charges must balance to

zero!)


BaCO3

Barium


BaCO3

Barium Carbonate


AlPO3


AlPO3

Aluminum


AlPO3

Aluminum Phosphite


H3PO4


H3PO4

Hydrogen

Naming Ionic CompoundsH3PO4

Think: H1+, we have 3 which

means +3, where will PO4

be?


H3PO4

Hydrogen Phosphate


FeSO4

Naming Ionic CompoundsFeSO4

Notice Iron appears in +2

and +3…


FeSO4

Sulfate


Since Sulfate is -2, Fe must be

+2


Iron(II) Sulfate


Iron(II) Sulfate or

Ferrous Sulfate

Practice Time!
