Compounds – Chemistry – 5th Outcome Sheet
10) Distinguish between ionic and molecular compounds, and describe the properties of some common examples of each
11) Read and interpret chemical formulas for compounds of two elements, and give the IUPAC (International Union of
Pure and Applied Chemistry) name and common name of these compounds (e.g., give, verbally and in writing, the name
for NaCl(s) (sodium chloride), CO2(g) (carbon dioxide), MgO(s) (magnesium oxide), NH3(g) (nitrogen trihydride or
ammonia), CH4(g) (carbon tetrahydride or methane), FeCl2(s) (iron(II) chloride), FeCl3(s) (iron(III) chloride), table salt
[NaCl(s)], water [H2O(l)], sodium hydroxide [NaOH(aq)] used in household cleaning supplies)
12) Identify examples of combining ratios/number of atoms per molecule found in some common materials, and use
information on ion charges to predict combining ratios in ionic compounds of two elements (e.g., identify the number of
atoms per molecule signified by the chemical formulas for CO(g) and CO2(g); predict combining ratios of iron and
oxygen based on information on ion charges of iron and oxygen)
13) Assemble or draw simple models of molecular and ionic compounds (e.g., construct models of some carbon
compounds using toothpicks, peas and cubes of potato)

Learning Activities
*Any definitions must be in your own words and have 2 examples – Use Frayer Model for tough ones.
Definitions: ionic compound, molecular compound, chemical formula, diatomic molecules, binary compound,
ion, conductivity
