1. Naming Compounds

2. Compounds Compounds = Chemical combinations of elements
Compounds = 2 or more atoms bonded together
All the compounds we will work with this year are called binary compounds (2 elements)

3. Examples NaCl C2H6 C6H12O6 Binary Compound Binary Compound
Not a Binary Compound

4. Naming a Binary Compound Step 1: Type of Bond
Ionic
Add or remove e-
Charged ions
No molecules
Metal + Nonmetal
Covalent
Share e-
Neutral atoms
Forms molecules
Nonmetals only ?
Before you name a compound you must determine the type of bond that holds it together

5. Naming a Binary Compound Option 1: Ionic Compounds
NaCl
Sodium Chlorine
Sodium Chloride
NaCl
Sodium Chlorine
Sodium Chloride
First, name the elements present
Then, change the ending of the nonmetal to “-ide”

6. Examples LiF CaO K2S AlBr3 Ga2O3 Lithium Fluoride Calcium Oxide
Potassium Sulfide
Aluminum Bromide
Gallium Oxide

7. Naming a Binary Compound Option 2: Covalent Compounds
First, name the elements present
Then, change the ending of the 2nd nonmetal to “-ide”
One more important step…
H2O
Hydrogen Oxygen
Hydrogen Oxide

8. Naming a Binary Compound Option 2: Covalent Compounds
H2O
Mono = 1
Di = 2
Tri = 3
Tetra = 4
Penta = 5
Hexa = 6
Hepta = 7
Octo = 8
Nano = 9
Deca = 10
Hydrogen Oxide
dihydrogen monoxide
Look at the subscripts and add the appropriate prefix to each word

9. Naming a Binary Compound Option 2: Covalent Compounds
Mono = 1
Di = 2
Tri = 3
Tetra = 4
Penta = 5
Hexa = 6
Hepta = 7
Octo = 8
Nano = 9
Deca = 10
C2H4
Carbon Hydride
dicarbon tetrahydride
Look at the subscripts and add the appropriate prefix to each word

10. Naming a Binary Compound Option 2: Covalent Compounds
Mono = 1
Di = 2
Tri = 3
Tetra = 4
Penta = 5
Hexa = 6
Hepta = 7
Octo = 8
Nano = 9
Deca = 10
CO2
Carbon Oxide
carbon dioxide
One last thing, the prefix “mono” is left off of the first element

11. Examples CH4 N2H2 C6H6 Si3Cl8 CO Carbon tetrahydride
Dinitrogen dihydride
Hexacarbon hexahydride
Trisilicon octochloride
Carbon monoxide
