Writing and Naming Ionic and Covalent Compounds
IMPORTANT!!! • FIRST, ALWAYS ASK YOURSELF, “IS THIS AN IONIC OR COVALENT BOND? ”
Writing Ionic Compounds • Rules 1. Write the symbol of the element (or polyatomic ion) that has the positive charge 2. Write the symbol of the element (or polyatomic ion) that has the negative charge 3. The charge (without the + or -) of one ion becomes the subscript of the other ion.
Writing Ionic Compounds Examples: 1. Sodium Chloride 2. Magnesium Bromide 3. Sodium Sulfide 4. Aluminum Chloride 5. Calcium Carbonate
Writing Covalent Compounds • Rules 1. Use the prefix in the name to tell you the subscript of each element in the formula. 2. Write the correct symbols for the two elements with the appropriate subscripts.
Prefixes • • 1 = mono 2 = di 3 = tri 4 = tetra 5 = penta 6 = hexa 7 = hepta 8 = octa
Writing Covalent Compounds Examples: 1. Carbon tetrabromide 2. Diphosphorus trioxide 3. Iodine dioxide 4. Phosphorus pentachloride
Naming Ionic Compounds • Rules 1. Write the name of the positive ion 2. Write the root name of the negative ion (first part of element’s name) and add “ide” to the end of it
Naming Ionic Compounds Examples: 1. Na. Cl = 2. Mg. Br 2 = 3. Na 2 S = 4. Al. Cl 3 = 5. Ca. Co 3 =
Naming Covalent Compounds • Rules 1. Name the first element listed in the formula putting the correct prefix in front of the name. If the prefix is “mono” you don’t need to write it! 2. Name the second element listed in the formula, putting the correct prefix in front of the name but change the ending to “ide. ”
Naming Covalent Compounds Examples: 1. CBr 4 = 2. P 2 O 3 = 3. IO 2 = 4. PCl 5 =
