Transfer goal: Attraction and repulsion
Apply the understanding of attraction between electrons and nuclei, as well as repulsion between electrons to explain in details the phenomena why water is polar and why ice is less dense than water.
- Atom structure
- Periodic trend: electronegativity
- Covalent bond: polar bonds
- Covalent structures: Geometry
- Intermolecular forces: Hydrogen bonding
Transfer goal: Colour in paints and pottery glazes
Make and use observations to identify and analyse the relationship between electron excitement in atoms/splitting energy in transition metals and light absorption to explain the various colours and colour changes in metal compounds that are used to make paints and pottery glazes.
