Finishing Up Ionic Bonds and Project Time Objective:
SWBAT find formula and name ionic bonds Catalyst:
What is an ionic bond? What is the oxidation number of Bromine? What is the formula for the ionic compound
formed between Magnesium and Fluorine?

You don’t know about transition metals! So.. the problem must tell you the
number of electrons. Cobalt (II) means that Cobalt gives
up 2 electrons

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.

MgF2 ???
NaBr ???
Naming Ionic Compounds
1)Write name of first element (metal).
2)Second element ends in -ide.
3)Ignore subscripts!

Ionic Cheat Sheets!
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 Compounds1) Look up the ions
on the cheat sheet and write the words next to
them.

Normally the first element is the first
piece and the rest is the second piece.

is +2, where should we find
the second?(Remember, charges must
balance!)

Think: H+, we have 3 which
means +3, where will PO4
be?

Notice Iron appears in +2

Since Sulfate is -2, Fe must be
+2
