1. Naming Ionic Compounds
Chemical Bonding

2. Lewis Structures

3. What to know about Ionic Bonds
Ionic compounds are made up of?
The electrons are being?
What is written first?
Opposite charges will?

4. How to write a formula S.O.S Ionic Formulas
Overall net charge must equal zero.
S.O.S
Symbols -> Oxidation # -> Simplify
Don’t show charges in the final formula.

5. Writing Formula Practice
Potassium Chloride
K Cl-1
 KCl
Aluminum Bromide
Al Br -1
 AlBr3
Beryllium Sulfide
Be S-2
 BeS (Simplify)

6. How to write a name
Write the name of the Cation (Metal) first. It comes straight off the periodic table.
Change ending of the Anion (Nonmetal) to end in - ide.
2Al O  Al2O3 Aluminum Oxide

7. Formula and Name Practice
2Al O  Al2O3 Aluminum Oxide
Formula
Name
Na3P
CaS
Sodium Oxide
Barium Phosphide
Lithium Nitride

8. How to write a formula with transition metals
When a Transition metal is involved in the bond, you must identify which form of the atom is bonding.
These atoms can have different oxidation numbers.
Look for the Roman Numeral in the name when writing the formula. The Roman numeral is the oxidation number of the transition metal.
Copper (II) Fluoride Cu F  CuF2

9. Writing Formula Practice
Copper (II) Fluoride Cu F  CuF2
Formula
Name
Copper (I) Oxide
Iron (III) Phosphide
Manganese (V) Fluoride
Zinc Phosphide
Nickel Oxide

10. How to write a name with transition metals
When naming the compound, you must balance the total charge, must be zero!
Look at the Anion. Determine the total sum of the charge provided by the Anion.
Look at the Cation. Remembering that the sum of the ionic compound must equal zero, determine the positive charge, and roman numeral.
Copper (II) Fluoride Cu F  CuF2

11. Writing Names Practice
Copper (II) Fluoride Cu F  CuF2
Formula
Name
Cu3N
Ti3P2
SnO
MnF3
TiO2

12. How to write a formula with polyatomic ions
If you have a compound with a polyatomic ion, the name will have a different ending using either (-ate) or (-ite)
Use your polyatomic ions chart to determine the ion
When writing formulas, keep these ions in parentheses if there is more than one polyatomic

13. Writing Formula Practice
Sodium Nitrate Na NO  NaNO3
Formula
Name
Magnesium Nitrate
Sodium Nitrite
Aluminum Phosphate
Barium Sulfate
Ammonium Fluoride

14. How to write a name with polyatomic ions
Look for more than two elements. That’s means a Polyatomic is present.
Match up the polyatomics and write the correct names and ending straight from the chart.

15. Writing Names Practice
Sodium Nitrate Na NO  NaNO3
Formula
Name
Na2SO4
Al2(SO3)3
CaCO3
NH4Cl
