1. Naming Ionic Compounds
Created by: Mrs. Susan Dube

2. Naming Ionic Compounds
The name of the ionic compound is based on the names of the ions it is made of.
For example, sodium ions bond with chlorine ions to make sodium chloride

3. Naming Ionic Compounds
To name an ionic compound, the name of the positive ion is placed first, followed by the name of the negative ion.
The negative ion’s name is changed from its original name by adding the suffix “ide.”
(copy into notes)

4. Ionic Compound Naming Practice
Remember, take the positive ion’s name and put it first.
Then, take the negative ion’s name and add “ide” to the end of it
Third, put the two names together and you have your compound’s name

5. Practice Naming Ionic Compounds
Potassium + Bromine = Potassium bromide
The positive ion is potassium, so we’ll keep that as the first name of our compound
The negative ion is bromine, so we’ll change that to bromide and add it to our positive ion to get our compounds’ name

6. Practice Naming Ionic Compounds
What ions are you dealing with? Remember, the number of protons tells you the atom’s identity!
Your positive ion is …
Your negative ion is …
Your ionic compound’s name is …

7. Practice Naming Ionic Compounds
Magnesium + Fluorine= Magnesium fluoride
The positive ion is magnesium because magnesium has 12 protons.
The negative ion is fluorine.
Your ionic compound’s name is magnesium fluoride.
