Forces Between Particles

In Year 12, we explored four types of substances: metallic, ionic, covalent networks, and molecular. We had to explain the properties of these using the particles they were made up of, and the forces (bonds) between these particles. We simply take this a step further in Year 13, focusing on ionic and molecular compounds. We start to use our deeper knowledge of atomic structure and shapes/polarity to explain differences (and peculiarities) in melting point (and boiling point) and solubility.

This video is an overview of the learning ahead. Each concept will be explored in more detail over the next two weeks.
