c2.3 predict the shapes of simple molecules and ions (e.g., CH4 , SO3 , O2 , H2O, NH4+), using the valence shell electron pair repulsion (VSEPR) model, and draw diagrams to represent their molecular shapes [AI, C]
c2.4 predict the polarity of various chemical com- pounds, based on their molecular shapes and the difference in the electronegativity values of the atoms [AI]
c2.5 predict the type of solid (ionic, molecular, covalent network, metallic) formed by a given substance in a chemical reaction, and describe the properties of that solid [AI]
c2.6 conduct an inquiry to observe and analyse the physical properties of various substances (e.g., salts, metals) and to determine the type of chemical bonding present in each substance [PR, AI]
C. Understanding Basic Concepts
By the end of this course, students will:
c3.1 explain how experimental observations and inferences made by Ernest Rutherford and Niels Bohr contributed to the development of the planetary model of the hydrogen atom
c3.2 describe the electron configurations of a var- iety of elements in the periodic table, using the concept of energy levels in shells and subshells, as well as the Pauli exclusion principle, Hund’s rule, and the aufbau principle
c3.3 identify the characteristic properties of ele- ments in each of the s, p, and d blocks of the periodic table, and explain the relationship be- tween the position of an element in the periodic table, its properties, and its electron configuration
c3.4 explain how the physical properties of a solid or liquid (e.g., solubility, boiling point, melting point, melting point suppression, hardness, electrical conductivity, surface tension) depend on the particles present and the types of intermolecular and intramolecular forces (e.g., covalent bonding, ionic bonding, Van der Waals forces, hydrogen bonding, metallic bonding)
c3.5 describe a Canadian contribution to the field of atomic and molecular theory (e.g., the work of Richard F.W. Bader of McMaster University on electronic density in small molecules; the work of Robert J. LeRoy of the University of Waterloo on the mathematical technique to determine the atomic radius of molecules known as the LeRoy Radius; the work of Ronald J. Gillespie of McMaster University on the VSEPR model)
