Curriculum content descriptions

The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186)

Elaborations
  • recognising that elements in the same group of the periodic table have similar properties
  • describing the structure of atoms in terms of electron shells
  • explaining how the electronic structure of an atom determines its position in the periodic table and its properties
  • investigating the chemical activity of metals
ScOT terms

Build an atom

This is an interactive resource that allows students to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can view the atoms using the electron shell model or cloud model. A small set of games give students the opportunity to review their understanding of how ...

Atoms of Fire: What makes salt and sugar so different?

Have you ever accidentally sprinkled sugar on your dinner or spooned salt into your coffee? Those white crystals might look the same but they taste very different because they are made of different kinds of atoms bonded in different ways. Discover how chemists identify what kinds of atoms a compound is made of, then find ...

Radio National: Using genes to unlock the secrets of Tutankhamen

Tutankhamen was an Egyptian pharaoh who ascended to the throne in 1333 BC, at the age or nine or ten. His fame in modern times is due to the discovery of his virtually intact tomb in 1922. Since then, many questions have been asked about his life and ancestry. Listen to this audio clip to find out how genetic technology ...

Catalyst: Chemical pollutants toxic to whales

Explore how chemical pollutants affect the Antarctic food web. A scientist shows that baleen whales are consuming Antarctic krill contaminated by accumulated residues of persistent organic pollutants (POPs) from pesticides and industrial chemicals. Find out why these pollutants are concentrated at the Earth's polar regions.

Catalyst: Nuclear fusion future

Visit the world's largest nuclear fusion reactor, which uses the same process as the Sun to produce energy. Look at the new advances in fusion technology which mean, for the first time, a fusion reactor should now be able to produce more energy than it consumes. It offers a future alternative energy source, but is not without ...
