1. Naming Compounds

2. Naming Ionic Compounds
Ionic compounds contain a metal and a nonmetal
Name the metal first, then the nonmetal as -ide
Examples:
NaCl sodium chloride
ZnI2 zinc iodide
Al2O3 aluminum oxide

3. What are the names of the following compounds?
Na3N
sodium nitride
KBr
potassium bromide
Al2O3
aluminum oxide
MgS
magnesium sulfide

4. Transition Metals
Most form more than one positive ions with these charges:
or or 3+
Ag Cd2+ Cu+, Cu Fe2+, Fe3+
silver cadmium copper(I) ion iron(II) ion
ion ion copper (II) ion iron(III) ion

5. Names of cations with more than one charge…
Use a Roman number after the name of a metal that forms two or more ions
Transition metals and the metals in groups 4A and 5A
FeCl3 (Fe3+) iron (III) chloride
CuCl (Cu+ ) copper (I) chloride
SnF (Sn4+) tin (IV) fluoride
PbCl (Pb2+) lead (II) chloride
Fe2S (Fe3+) iron (III) sulfide

6. Name the following compounds:
CaO
calcium oxide
SnCl4
tin(IV) chloride
Co2O3
cobalt (III) oxide

7. Complete the names of the following
compounds with variable metal ions:
FeBr2
iron (II) bromide
Cu2O
copper (I) oxide
SnCl4
tin (IV) chloride
Fe2O3
iron (III) oxide
CuS
copper (II) sulfide

8. A group of atoms with an overall charge. Refer to your handout…
Polyatomic Ions
A group of atoms with an overall charge. Refer to your handout…
NH4+ Ammonium
OH- Hydroxide
NO3- Nitrate
NO2- Nitrite
CO32- Carbonate

9. Naming Ternary Compounds
Contain at least 3 elements
Name the nonmetals as a polyatomic ion
Examples:
NaNO3 Sodium nitrate
K2SO4 Potassium sulfate

10. Identify the correct names:
Ca(HCO3)2
calcium bicarbonate
CaCO3
calcium carbonate
Ca3(PO4)2
calcium phosphate
Na2CO3
sodium carbonate
MgSO3
magnesium sulfite
MgSO4
magnesium sulfate

11. Naming Covalent Compounds
Two nonmetals
End the last element in -ide
Add prefixes to show more than 1 atom
Prefixes:
mon penta- 5
di- 2 hexa- 6
tri- 3
tetra- 4

12. CO
carbon monoxide
CO2
carbon dioxide
PCl3
phosphorus trichloride
CCl4
carbon tetrachloride
N2O
dinitrogen monoxide

13. Acids without the presence of oxygen, the name is written as:
Hydro(anion)ic acid
Hydrosulfuric acid – H2S
Hydrobromic acid - HBr
Hydrocyanic acid – HCN

14. If the anion ends in “-ite”, the suffix is “-ous”
If the acids do contain oxygen, the method of naming them changes. If the anion ends in “-ate”, the suffix that is added to the chemical name is “-ic”.
Nitric acid HNO3
Sulfuric acid H2SO4
Phosphoric acid H3PO4
If the anion ends in “-ite”, the suffix is “-ous”
Nitrous acid HNO2
Sulfurous acid H2SO3
