 Take out a pen/pencil
 Three colors (crayon, colored pencils, markers)
On the top flap of your flip book write
 “Chemical Naming Flip Book”
 Name
 Period
Label the tabs of your
flip book according
to the diagram on the
right.

Polyatomic ions/Periodic Table
 Color 1: Shade in
elements in group 1 and 2
(not hydrogen) as well as
Ag, Zn, Al
 Color 2: Shade in the non
metals (elements to the
right of the stair step and
hydrogen)
 Color 3: All other metallic
elements
 Make the following Key at
the bottom:
Ionic compound, no roman numeral
Ionic compound, use roman numeral
Molecular compound, use prefixes
 Group 1 = +1
 Ag +1
 Group 2 = +2
 Zn +2
 Group 8 = 0
 Al +3
 Group 7 = -1
 Group 6 = -2
 Group 5 = -3
 Add the diatomic molecules:
 Methane = CH4
 Ammonia = NH3
 I2, Br2, Cl2, F2, O2, N2, H2
 Add Cyanide = CN- to -1 Ions
Step One: Name the cation and anion (in that order)
 Recall – Anions end in –ide unless they are polyatomic ions
ex) FeCl3
iron chloride
Step Two: Figure out if you need a Roman numeral in the name.
Look at the back page of your flip book and see if it needs a Roman
numeral. If it is a transition metal, it probably does.
 Ex) Yes, this one does.
Step Three: Figure out what the Roman numeral should be
The charges in an ionic compound must add up to zero.
 Reverse the “Swap and Reduce” – but make sure the charge on the ion is correct
 Mathematically determine the charge
 Fe+??
3 Cl-1 = -3
 Iron (III) Chloride
Fe must be 3+ to make the charge add up to zero
MgBr2
V2O5
CuSO4
Cu2O
 Step One: Translate the name into the ions. Don’t skip this step.
 The roman numeral tells the charge of the ion for transition metals. If no charge given, use the
periodic table to determine.
Ex) copper (II) fluoride
Cu+2
F-1
 Step Two: Swap and Reduce
 Cu+2 F-1
CuF2
 Step Three: Put parenthesis around the polyatomic ion if necessary after swapping
 It is needed when you swap down a number to a PAI other than 1.
 Ex) calcium hydroxide
Ca+2 OH-1  Ca(OH)2
 Step Four: Reduce if necessary
 Looking only at the numbers you swapped (not numbers part of the polyatomic ion), make
sure they are in the lowest possible ratio.
 Ex) Sn2S4  SnS2
 Ex) Fe2(SO4)2  FeSO4

To name a molecular compound, write two words:
Prefix + Name of first nonmetal
+
Prefix + Name of second nonmetal + ide
Exceptions:
- don’t write mono- if there is only one of the first element.
- don’t use the following double vowels when writing names (oa oo)
Cl2O7 = dichlorine heptoxide
CBr4 = carbon tetrabromide
 Use the prefixes given in the name to determine how many
of each type of atom you have.
 Do not reduce (like ionic compounds)
 tetraiodine nonoxide = I4O9
 sulfur hexafluoride = SF6
