explain how the structure and properties of atoms relate to the organisation of the elements in the periodic table (AC9S10U06)

Elaborations
  • examining how elements are organised in the periodic table and analysing patterns to discern that elements in the same group of the periodic table have similar properties
  • investigating the physical properties of some metals and non-metals
  • using the Bohr model of the atom to describe the structure of atoms in terms of electron shells and relating this to their properties and position in the periodic table
  • deducing that repeating patterns of the periodic table reflect patterns of electrons in outer electron shells
  • conducting flame tests for a selection of elements and examining emission spectra
  • examining how the development of the spectroscope led to further development of the model of the atom
General capabilities
  • Critical and creative thinking Critical and Creative Thinking

Build an atom

This interactive simulation explores atomic structure, elements and the periodic table. In a series of simulations students use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge; predict how addition or subtraction of a proton, neutron, or ...

Interactive

Isotopes and Atomic Mass

This interactive simulation explores isotopes and how the average atomic mass of an element changes given a change in the abundance of its isotopes. In a series of simulations students explore the stability of various isotopes and investigate how this relates to the proportions of isotopes in naturally occurring elements. ...

Interactive

Build a Nucleus

This interactive simulation explores isotopes and nuclear decay. In a series of simulations students explore how the changing the number of neutrons or protons affects the atomic number and isotope; investigate and predict how the shell model depiction of an isotope based on the isotope symbol or name; and predict the resulting ...

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 ...
