Module 2 | Metals

Focus 3: As metals and other elements were discovered, scientists recognised that patterns in their physical and chemical properties could be used to organise the elements into a Periodic Table

Lesson 1 | Development of the periodic table

  • Identify an appropriate model that has been developed to describe atomic structure.

  • Outline the history of the development of the Periodic Table including its origins, the original data used to construct it and the predictions made after its construction.

  • Process information from secondary sources to develop a Periodic Table by recognising patterns and trends in the properties of elements and use available evidence to predict the characteristics of unknown elements both in groups and across periods.

Lesson 2 | Trends in the periodic table

  • Explain the relationship between the position of elements in the Periodic Table, and:
    – electrical conductivity
    – ionisation energy
    – atomic radius
    – melting point
    – boiling point
    – combining power (valency)
    – electronegativity

  • Use computer-based technologies to produce a table and a graph of changes in one physical property across a period and down a group.
