Outcome: CH30‐MS2 Investigate how the properties of materials are dependent on their underlying intermolecular and intramolecular forces.[SI]
B. Differentiate between the different types of intermolecular (i.e., van der Waals [i.e., London dispersion, dipole‐dipole, hydrogen bonding and ion dipole], ionic crystal and network‐covalent) and intramolecular (i.e., nonpolar covalent, polar‐covalent, ionic and metallic) forces.
C. Recognize that a material’s chemical and physical properties are dependent on the type of bonds and the forces between atoms, molecules or ions. (K)
D. Identify and describe some properties (e.g., melting point, solubility, thermal conductivity, electrical conductivity, hardness, heat capacity, tensile strength, surface tension, reactivity with acids and bases, flammability, flame tests and odour) of ionic and molecular compounds, metals and network covalent substances. (S)
F. Construct a classification system of student‐tested materials according to one or more properties. (S, STSE, A)f. Construct a classification system of student‐tested materials according to one or more properties. (S, STSE, A)
Today we finished off our unit by learning about the intermolecular forces present in covalent molecules. We then looked at the properties of molecular covalent and network covalent compounds. We also summarized the properties in a nice little table.
After the notes we sorted cards into categories of ionic, metallic, molecular covalent or network covalent. We then used to the cards to create flipbooks and used the flipbooks to create a flow chart for identifying solids using properties. This flow chart will be used in tomorrow’s lab.
You should now be able to finish all of the assignments from the booklets for this unit and the practice exam (due Thursday).
