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.
