1. Honors Unit 4
Nomenclature

2. 4.1 Naming Binary compounds
Binary compounds – contain two different elements
Three types
Type 1: metal can only form one cation
MgO
K2S
Type 2: metal can from two or more cations that have different charges
FeO
Fe2O3
Type 3: contain only nonmetals
CO2
PCl5

3. Naming Compounds That Contain a Metal and a Nonmetal

4. Naming Compounds That Contain a Metal and a Nonmetal
Type I Binary Ionic compounds

5. Naming Compounds That Contain a Metal and a Nonmetal
For compounds containing both a metal and a nonmetal, the metal is always named first. The nonmetal is named from the root element name.

6. Name the following compounds
CsF
AlCl3
MgI2
K3N

7. When writing formulas of ionic compounds the net charge must be zero!
To write formulas from names:
Identify the ions involved and write their symbols
Combine the ions to create an atom with a net charge of zero

8. Write the formula from the name:
Calcium iodide
Sodium oxide
Aluminum nitride
Strontium phosphide

9. Naming Compounds That Contain a Metal and a Nonmetal
Type II Binary Ionic compounds
Since the metal ion can have more than one charge, a Roman numeral is used to specify the charge.

10. Naming Compounds That Contain a Metal and a Nonmetal
Type II Binary Ionic compounds

11. Write the formula for the following
Iron (III) Iodide
Titanium (III) Oxide
Chromium (III) Phosphide
Copper (I) Chloride
Tin (IV) Sulfide

12. Name the following
FeCl2
PbO2

13. Name the following
FeS
CuCl
Hg2O
SnS2

14. Naming Binary Compounds That Contain Only Nonmetals (molecular compounds)
Type III Compounds

15. Naming Binary Compounds That Contain Only Nonmetals
Type III Compounds

16. Name The Following: CO
H2O
Si3O6
P2Cl5

17. Writing formulas from names for type III
Use the prefixes in the name to tell how many of each atom there are in the compound
DO NOT balance out charges as you do with Ionic compounds

18. Write the formula from the name
Carbon Tetrachloride
Sulfur Hexaflouride
Tetraphosphorus Decoxide
Dinitrogen Monoxide

19. Naming Binary Compounds: A Review

20. Naming and Writing formulas for more Complex Compounds

21. Naming Compounds That Contain Polyatomic Ions
Polyatomic ions are charged entities composed of several atoms bound together.
They have special names and must be memorized.

22. Naming ionic compounds containing polyatomic ions follows rules similar to those for ionic binary compounds. But do not change the ending to -ide
ammonium acetate

23. Name the following:
KOH
Ca(NO3)2
Na2SO4
(NH4)3PO4

24. When writing formulas from names balance charges as you do with ionic compounds
Sodium Phosphate
Calcium Nitrate
Aluminum hydroxide
Potassium carbonate

25. Naming Acids
An acid is a molecule with one or more H+ ions attached to an anion.

26. Naming Acids

27. Naming Acids
