Stage 4

Periodic table and atomic structure

Working scientifically

In this focus area, students develop skills in processing and analysing data and information. Additional Working scientifically outcomes and skills may be integrated with this content.

Loading 
Classification of matter
  • Identify some common Loading  in everyday objects

  • Conduct a series of investigations to identify and compare the physical Loading  of metals, non-metals and Loading 

  • Explain how the properties of some common elements, Loading  and Loading  Loading  to their use(s)

Atomic structure
  • Identify the atom as the smallest unit of an element that retains the properties of that element

  • Identify protons, neutrons and electrons as Loading  particles

  • Describe the location, relative charge and Loading  of protons, neutrons and electrons using the planetary atomic Loading 

  • Outline how models of atomic structure have changed over time

  • Explain how Loading  made possible by new technologies have led to a more detailed understanding of atomic structure

Periodic table
  • Outline patterns and relationships found in the Loading , including reactivity

  • Predict the properties of elements based on their position and location on the periodic table

  • Identify the unique symbol of a range of elements

  • Use the periodic table to identify the elements in some common compounds

  • Loading  some tests that could be used to identify metal and non-metal elements

  • Model the atomic structure of the first 18 elements to identify that atomic structure changes with increasing Loading 

  • Describe how the historical development of the periodic table demonstrated understanding of the chemical and physical properties of elements

Periodic table and atomic structure in context
  • Investigate how the properties and availability of materials, including metals, alloys and compounds, influence their uses
