Our DP Chemistry students have been making excellent progress as we navigate Structure 2 of the curriculum. This unit is fundamental to understanding how the microscopic arrangement of atoms dictates the macroscopic properties of the materials we use every day.
In Grade 11, we have successfully concluded our deep dive into Ionic Bonding. Students have explored how the transfer of electrons creates strong electrostatic attractions, resulting in the characteristic properties of giant ionic structures, such as high melting points and brittleness. We have also transitioned into Covalent Bonding, examining how atoms share electrons to reach stability, including the unique cases of coordinate (dative) bonding.
Starting next week, we will shift our focus to Electronegativity and Bond Polarity. This is a pivotal topic where students will learn why some molecules have “charged sides” and how this affects their behavior in the physical world.
Please take note of the following key date:

End of Unit Test: Tuesday, 18th February
This assessment will cover all aspects of bonding and structure discussed so far. We encourage students to begin reviewing their notes on ionic and covalent properties early to ensure they are prepared for the application-based questions typical of the DP level.
