Materials and their atoms

Connect material evidence, atomic structure, quantities and periodic patterns.

Subtopics

Match material uses to physical properties and apply nanoparticle size rules.

Match filtration, evaporation, distillation and chromatography to mixtures.

Read isotope notation, count subatomic particles and interpret atomic evidence.

Build electron configurations through element 38 and recognise important exceptions.

Convert between mass, amount and number of atoms with explicit units.

Use mass spectra and abundance data to calculate weighted atomic masses.

Relate electron arrangements to position, radii, electronegativity and valency.

Identify all four periodic blocks and apply common introductory valency patterns.
