Chapter #5Nomenclature
Binary means two different elements
Ionic means metal and nonmetal
Step 1First give the name of the metal, followed by thenonmetal name using the “ide” suffix.
Step 2 If the metal is to the right of group IIA, then aRoman numeral is used after the metal to todescribe the charge of the metal. Except Ag,Zn,and Al
Examples
NaCl Al2O3
FeCl2 FeCl3

III. Binary molecular Compounds
Step 1First give the name of the first nonmetal,followed by the nonmetal name using the “ide”
suffix.Step 2
Give each nonmetal a Latin prefix describing the number of atoms present in the compound.
ExamplesCO CO2
P2O5 CCl4
Molecular means nonmetals
You will need to learn the Greek numerical prefixes (Table 4.6):
Number Prefix
1 Mono-*
2 Di-
3 Tri-
4 Tetra-
5 Penta-
6 Hexa-
7 Hepta-
8 Octa-
9 Nona-
10 Deca-
*Note 1 Compound names never start with mono
Note 2 When adding a prefix two vowls cannot next to each other

III. Nonbinary Molecular Compounds
Step 1
Write down the memorized polyatomic ions present in the compound.
Step 2
Look to see if any monatomic ions are present. If so, then cations use the normal name. If it is an anion, then its name comes last with the “ide” suffix.
Examples
NH4Cl
NH4OH
Note: Do not use Latin prefixes
III. Nonbinary Molecular Compounds

Compounds that Start with HydrogenCase 1
Case 2
Case 3
Case 4
If the anion ends in “ide” and it is aqueous, then use the prefix hydro and suffix “ic acid”
If the anion ends in “ate” then drop it and add the suffix “ic acid”
If the anion ends in “ite” then drop it and add the suffix “ous acid”
If the anion ends in” ide” and is a gas, or liquid, then leave the name and do not use Latin prefiex
