Name: ______Date: ______

Exercise 1: Distinguishing between ionic and molecular compound and learning about charges of ions

Remember: if the compound contains all NON-METAL atoms, then it is MOLECULAR.

Compound Name / Chemical Formula / Ionic or Molecular
Calcium chloride / CaCl2
Iron (III) oxide / Fe2O3
Carbon monoxide / CO
Water / H2O
Magnesium sulfate / MgSO4
Oxygen gas / O2
Ammonia / NH3

Exercise 2: Reviewing the CHARGES of METAL and NON-METAL ions

Element / Atomic Symbol / Number of Valence Electrons / # of electrons gained, or lost / Charge (oxidation #)
Potassium
Sulphur
Iodine
Aluminum
Beryllium
Argon
Silicon

Show HOW an ionic compound is formed between Aluminum and Sulphur. You must show electron transfer from a metal to a non-metal.

Naming Binary and Multivalent Ionic Compounds

Exercise 3: Writing formulas for IONIC COMPOUNDS

Metal + non-metal / Charge on metal / Charge on non-metal / Criss-cross (show work) / Ionic formula
Calcium + nitrogen
Lithium + bromine
Aluminum + phosphorus
Iron (III) + oxygen
Manganese (IV) + sulphur
Strontium + selenium
Gold (III) + iodine
Titanium (II) + carbon

Writing NAMES for ionic compounds

Rules:

1.  Identify the positive ion (metal ion) and the negative ion (non-metal ion) first.

2.  Always name the metal FIRST.

3.  If the METAL is a multivalent transition metal, then indicate in the brackets the Roman numeral that corresponds to the charge. Example: Fe2+ iron (II) and Fe3+ iron (III)

4.  Name the non-metal SECOND, but change the name of the non-metal so that it ends in IDE. Example: chloride, sulphide, oxide, iodide, nitride, carbide, etc.

Exercise 4: Provide the name for the following binary and multivalent ionic compounds

IUPAC stands for International Union of Pure and Applied Chemists

Binary Ionic / IUPAC Name
