1. Warm up 10-12-15 Covalent bonds are between _____ and _____ elements
Ionic bonds are between _____ and _____ elements
Identify if these compounds are ionic or covalent: FeS, CO2, Cl2 and AlBr3

2. Formulas and Names of Ionic and Covalent Compounds
Chp 5-3 and 6-2

3. Nomenclature: Naming of compounds
Must determine which type of bond made up the compound
Ionic bond has metal elements
Covalent bond has no metal elements

4. Naming Covalent (Molecular) Compounds
1. Use a prefix to indicate the amount of each element in the compound 2. Never use mono– on the first element name. 3. Give the last element an –ide ending.

5. Naming Covalent (Molecular) Compounds
Mono– 1
Di– 2
Tri– 3
Tetra– 4
Penta– 5
Hexa– 6
Hepta– 7
Octa– 8
Nona– 9
Deca– 10
Prefixes

6. Examples
CO2
B2H4
Dinitrogen trioxide

3. SiO2
4. SCl4 5.
Trinitrogen pentabromide 6.
Dinitrogen trioxide
Why incorrect?
Monosulfur dioxide
Carbon Monoxide, diphosphorus pentasulfide, Silicon dioxide, sulfur tetrachloride, N3Cl5,

8. Naming Ionic Compounds
1. Ending element change to –ide. (no prefixes)
2. Make sure all the charge cancel each other out
3. If there is a transition metal you indicate the charge with a roman numeral after the name of the metal.
4. If it is a polyatomic ion, you simply use the name as it is. (no –ide)

9. Examples CaCl2 MgI2 Potassium Sulfide Beryllium Fluoride
Iron (II) Nitride
FeCl2
