3. Agenda Catalyst/Announcements Homework Check
Notes: Ionic Compounds, Ionic Bonding

4. Example: Ionic Bonding
Na+
Cl -
All ionic compounds are composed of a positive ion and a negative ion.
Ionic compounds are always neutral, meaning their charges cancel each other out.
The result is an ionic compound with a NET CHARGE of zero.
1+ and 1- = zero
Formula = NaCl

5. Check for Understanding
Match the cation with the anion it will MOST likely form a bond with: Cation Anion Al3+ P3- Mg2+ Cl- K+ S2-
Formula = AlP
Formula = KCl
Formula = MgS

6. Ionic Bonding
What if the charges of each ion did NOT cancel one another out? (Remember NET CHARGE = 0) Mg2+ and Cl- 
(2) = 0 
MgCl2
Write the # after the ion as a subscript!!
= 0

7. Check for Understanding
Mg2+ and P3- Al3+ and O2- 
2+(3) + 3-(2) = 0 
Mg2P3 
3+(2) + 2-(3) = 0 
Al2O3

8. Properties of Ionic Compounds
1.) Most ionic compounds are crystalline solids at room temperature. Because of this structure ionic compounds are called salts.
Barite (BaSO4)
Aragonite (CaCO3)

9. Ionic Compounds
Most rocks, minerals and gemstones are ionic compounds.
Ceramics, bricks and kitchen crockery are made from clays which contain ionic compounds.

10. Properties of Ionic Compounds
2.) Unlike metals, ionic compounds are not malleable. They break when a force is applied.

11. Properties of Ionic Compounds
3.) Most ionic compounds have high melting and boiling points. *Example: Salt (NaCl) melts at 800°C.

12. Properties of Ionic Compounds
4.) Ionic compounds can conduct an electric current when melted or dissolved in water. *note: ionic compounds CANNOT conduct electricity in their solid state

13. - Page 198
Ions are free to move when they are molten (or in aqueous solution), and are able to conduct an electric current.

14. Ionic Compound Puzzle Game
Using the puzzle pieces, you will come up with as many ionic compounds as possible.
Charges MUST be neutral!
Can only have two different ion together.
When naming, name the cation first!

Cation Name
# of Cations
Anion Name
# of Anions
Chemical Formula
Ionic Compound Name

Finish: Creating ionic compounds puzzle
Notes: Drawing Lewis Dot Structures of Ionic Compounds

21. Reminders on IONIC COMPOUND
An IONIC compound consist of a cation (metal) bonded with an anion (non-metal)
An IONIC bond results from a TRANSFER of electrons.

22. Rules for Drawing Lewis Dot Structures for Ionic Compounds
The cation has NO dots around the symbol and the anion has 8 dots around the symbol.

23. Rules for Drawing Lewis Dot Structures for Ionic Compounds
If the compound has ONLY one cation and one anion the cation ALWAYS goes first. Brackets go around the anion to show possession of electrons.
Ex: NaCl is ALWAYS drawn as
Na+ Cl -

24. Rules for Drawing Lewis Dot Structures for Ionic Compounds
If the compound has MORE than 2 atoms, draw the structure so it looks even.
Ex: Al2O3 = O 2-Al3+ O 2-Al3+ O 2-
*If you were able to cut the structure in half, you should be holding the same piece in both hands!!!

25. Rules for Drawing Lewis Dot Structures for Ionic Compounds
The cation must lose ALL of their valence electrons and the anion must have 8 to obey the Octet Rule.

26. Rules for Drawing Lewis Dot Structures for Ionic Compounds
Each cation should touch each anion it donates electrons to.
Therefore: Two cations should never touch and two anions should never touch.
