Grade 10 Science: Nomenclature of Chemical Compounds Package Mr.Krstovic

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 Number of # of electrons gained, Charge Symbol Valence or lost (oxidation #) Electrons 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- Charge on metal Charge on non- Criss-cross Ionic formula metal metal (show work) 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
