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

Properties of matter,  Atoms

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 ...

Measuring gravity

Did you know you can measure gravity? The more mass an object has, the more gravity it has, so by measuring the mass of something, you can figure out its gravity. Why do you think climate scientists may want these measurements? Watch this NASA animation to find out.

Exploring atoms: atom structure

See how scientists such as Ernest Rutherford have investigated the structure of atoms. Explore possible models. Fire charged particles at atoms and find which model best fits the results. This learning object is one in a series of six objects. Three of the objects are also packaged as a combined learning object.

How does the retina work?

When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!
