Naming Ionic Compounds Created by: Mrs. Susan Dube

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 (copy into notes)

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)

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

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

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 …

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.

Quick Check for Understanding Name the ionic compounds formed: Calcium + Sulfur = Beryllium + Chlorine = Potassium + Fluorine = Sodium + Chlorine = Lithium + Iodine = Magnesium + Sulfur =
