1. The Joy of Ions and the Importance of Electrons notes start date:_____ 4.10, 4.11, 5.1, 5.2
click me and minimize first :)

2. Isn’t it ionic… It’s like raaaiiiin on your wedding day!
Ok maybe not quite.
But I bet you’ll think about
ions the next time you hear
this Alanis Morissette song 

3. Mommy, how are ions made?
An ion is an atom or molecule that has a charge from gaining or losing 1+ e’s
Atoms will form ions when a metal bonds with a nonmetal

4. The talk continues…
cation – positively charged ion produced when electrons are
lost from neutral atom

5. The talk continues…
anion – negatively charged ion produced when electrons are
gained from neutral

6. Well that’s all well and good Mommy, but how are ions named?
cations
name = name of element + “ion”
ex. Mg2+ is called “magnesium ion”
anions
name = root of element name + “ide”
ex. Cl- is called “chloride”

7. Now you try! Name the following cations and anions: Na+ Li+ Ca2+ Br-

8. Knowing what ions will form
Figure 4.19 on p. 109 is a great reference
Table 5.1 on p. 125 as well
Groups 1, 2 and 3 form 1+, 2+ and 3+ cations
(Hydrogen forms both H+ and H-)
Group 7 metals form 1- anions, Group 6 metals form 2- anions

9. Ball time
Everybody needs their periodic table out 

10. Ionic Compounds
Ionic compounds contain both a ______ and a _______ and are _______ overall.
Salt, NaCl is an example of a common ionic compound.
What is the cation here?
What is the anion here?

11. Special properties of ionic compounds
Ionic compounds have very high boiling points. Example: They conduct electricity when dissolved in water b/c the compound dissolves into its ions

12. That’s all well and good, Mommy, but how are ionic compounds named?
Binary ionic compounds – 1 cation + 1 anion = 2 ions overall, hence binary
Type 1: a non-transition metal plus a non-metal
when 2 becomes 1

13. Naming Type I Binary Ionic Compounds
Say the name of the metal element
Now say the name of the nonmetal anion
Ex: KBr is potassium bromide

14. Now you try: CsCl MgO BeS
In your notes, name the following binary ionic compounds:
CsCl
MgO
BeS

15. Naming Binary Ionic Compounds that contain Transition Metals
transition metals- the metals in the middle rectangle of the periodic table, most form
_________ cations
Ex:
Fe3+ is iron(III)
Fe2+is iron( )

16. To name ionic compounds containing transition metals…
Say the _______’s name, followed by ________
Now say the name of the ________
Ex:
Fe2O3: iron(III) oxide
MnO2: manganese(IV) oxide

17. Figuring out the charge on the cation
Look at the chemical formula, and figure out the __________________
Figure out what the charge on the cation must be so that the overall charge is ________.

18. Example time! Two together.
PbCl4
The anion is Cl-
The charge on the anion is ____.
____ x ____ = 0
The charge on the cation is ____. The name of this compound is lead( ) chloride.

19. Example time! Two together.
MnO2
The anion is ____
The charge on the anion is ____.
___ + (2 x ____) = 0
The charge on the cation is ____. The name of this compound is manganese( ) oxide.

20. Now you try! What are the names of the following compounds? PbBr4
CoCl3
FeS

21. Use table to come up with binary ionic compounds
BINGO time!!
Use table to come up with binary ionic compounds
Write compounds (formulas) in bingo board
Play for chocolate
