Chemistry Exercise

Determine the chemical formula for the following ionic compounds:Sodium Chloride Ammonium OxideMagnesium Fluoride Copper (I) ChlorideCalcium Oxide Copper (II) ChloridePotassium Sulfide Magnesium SulfateAluminum Chloride Aluminum NitrateAluminum Oxide Tin (IV) Carbonate

Properties of Ionic Compounds

1. All ionic compounds form crystals. 2. Ionic compounds tend to have high melting

and boiling points. 3. Ionic compounds are very hard and very

brittle. 4. Ionic compounds conduct electricity when

they dissolve in water.

Rules for Naming Ionic Compounds

1. The name of the cation always comes first.2. If the cation is a transition metal, then a

Roman Numeral is used after the cation to indicate it’s charge.

3. The name of the anion always comes second.4. If the anion is an element, the ending of the

name is changed to –ide.
