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

Amazing materials from rearranged carbon atoms

Explore the different forms (allotropes) of the chemical element carbon. You will be surprised at how different the allotropes are.Meet key scientists, such as Harry Kroto, who have made amazing discoveries about new forms of carbon. Visualise how the atoms and outer electrons are arranged in different forms, so you can ...

Precious metals

Why are some metals prized more for jewellery than others? Listen to presenter Bernie Hobbs explain the chemical reaction that affects the look and durability of metals. Using the periodic table and some dazzling computer graphics, Bernie demonstrates why 'oxygen-proof, low-reactivity, transition metals' such as gold keep ...

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 ...

When neutron stars collide

Using technologically advanced supercomputers, scientists have developed theories about the creation of black holes deep in outer space. Watch the computer simulation in this clip to see how the collision of two neutron stars produces a gamma ray burst and a new black hole. Discover that our continuing understanding of ...

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.

Forensics track drugs back to their origin

Scientists are helping police to identify the place of origin of illicit drugs that arrive on Australian shores. Watch this clip to find out how scientific analysis, computer databases and police investigation are used together to determine the source of drugs such as cocaine. Discover that international efforts are involved ...

Video

Gamma rays and space balloons

Have you ever wondered how scientists know so much about the universe when it's too far away to see and no one has ever been there? It's not just by using telescopes based on Earth. Watch as an international team of astrophysicists and engineers attempt to launch a balloon high into the atmosphere, loaded with expensive ...

Dyeing with red cabbage!

Many natural products, such as red cabbage and turmeric, can be used as a natural source of colour to dye fibres. Watch the dyeing demonstration in this clip to see how. Discover the chemistry of natural dyes, including the bonding properties of different pigments and how acid-base reactions can alter the colour of pH-sensitive ...

Video

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!

Video

Large Hadron Collider discovery, 2012

Have you heard of the Large Hadron Collider (LHC)? Watch this clip to find out about a scientific discovery at the LHC that left physicists uncharacteristically emotional. Catalyst's Dr Derek Muller takes you inside the LHC and talks to scientists there about the discovery of the Higgs boson and what it means for our understanding ...
