Secondary 4 Chemistry
This course explores the fundamental principles governing matter and its changes. Students analyze chemical systems through the lens of kinetic particle theory, stoichiometry, and energy changes to predict and explain the behavior of substances in real world contexts.
Atomic Architecture and Chemical Bonding
Investigation into how subatomic arrangements determine the physical and chemical properties of elements and compounds.
Exploring the distribution of electrons and the significance of valence shells in chemical reactivity.
Analyzing the electrostatic forces that hold different types of matter together.
Examining the 'sea of electrons' model and its impact on the physical utility of metals.
The Language of Chemistry: Stoichiometry
Quantitative analysis of chemical formulas and equations to predict the yields of reactions.
Bridging the gap between the microscopic world of atoms and the macroscopic world of grams.
Calculating theoretical yields and identifying limiting reagents in chemical processes.
Using volumetric analysis to determine the precise concentration of aqueous solutions.
Chemical Energetics and Kinetics
Exploring why reactions happen at different speeds and how energy is exchanged with the surroundings.
Differentiating between exothermic and endothermic reactions through bond energy analysis.
Investigating the factors that influence the frequency and success of molecular collisions.
Analyzing how catalysts provide alternative pathways to speed up chemical transformations.
Patterns in the Periodic Table
Understanding the systematic trends and properties of elements based on their position in the table.
Comparing the reactivity and physical properties of Group 1 and Group 17 elements.
Exploring the unique properties of d-block elements including variable oxidation states and colored compounds.
Tracking the transition from metallic to non-metallic behavior across a single period.
Acids, Bases, and Salts
Investigating the chemistry of protons and the synthesis of ionic compounds.
Defining acidity and alkalinity through ion concentration and pH scales.
Mastering the techniques for synthesizing pure, dry samples of various salts.
Using chemical tests to identify unknown cations, anions, and gases.
Redox and Electrochemistry
Analyzing reactions involving electron transfer and the conversion between chemical and electrical energy.
Identifying oxidation and reduction in terms of oxygen transfer, hydrogen transfer, and electron movement.
Using electricity to drive non-spontaneous chemical decompositions.
Exploring how spontaneous redox reactions generate an electric current.
