1. Ionic Compounds: Naming

2. Naming Binary Ionic Compounds
Always name metal (the cation/+ ion) first
2. Write stem of nonmetal (the anion/ - ion)
3. Add ending “ide” to nonmetal
Binary =
only 2 types
of elements
(two capital letters)

3. Stems of nonmetals Iod Brom Chlor Fluor Hydr is the stem for H Tellur
Selen
Arsen
Sulf
Phosph Ox
Nitr

4. Metals with one oxidation state
CaO
BaS
AlN
LiCl
Al2Se3
Na2O
K3N
MgF2
Calcium Oxide
Barium Sulfide
Aluminum Nitride
Lithium Chloride
Aluminum Selenide
Sodium Oxide
Potassium Nitride
Magnesium Fluoride

5. The First Step in Naming
Find metal on PT
If metal has only one oxidation state it’s easy
If metal has more than one oxidation state, there’s an extra step

6. Metals with > 1 oxidation state
Use formula to figure out which oxidation state metal ion has
Ex: Fe can be Fe+2 or Fe+3
Name FeO and Fe2O3

7. FeO
Name: Iron (II) oxide
(roman numeral II = charge on Fe)

8. Fe2O3
Name: Iron (III) oxide
(roman numeral III = charge on Fe)

9. Name the following TiCl3 MnO2 AuCl3 MnO Titanium (III) chloride
Manganese (IV) oxide
Gold (III) chloride
Molybdenum (III) nitride

10. Naming compounds with polyatomics
If it contains a polyatomic, same rule, just write the name polyatomic ion (Table E)

11. Name the following NaOH LiNO3 Al(NO3)3 Fe(OH)2 Sodium hydroxide
Lithium nitrate
Aluminum nitrate
Iron (II) hydroxide
