KS3 & KS4 science curriculum

This unit builds on pupils’ prior learning from Patterns in the periodic table, where they explored how atomic structure determines element properties and reactivity trends. It deepens their understanding by focusing on the specific properties and reactions of elements in Groups 1, 7, and 0 of the periodic table. This prepares pupils for the next unit, Chemical analysis, where they will apply their knowledge of element groups to identify substances using techniques such as flame tests and instrumental methods, reinforcing their understanding of element behaviour and analysis.

1. Properties of Group 0
2. Properties of Group 1
3. Properties of Group 7
4. Reactions of the halogens: including displacement practical
5. Ionic equations: reactions of Group 1 and Group 7

• Group 0 elements are called noble gases and do not react.
• The elements in Group 1 are all soft metals that float on water.
• Group 1 metals get more reactive as you go down the group.
• As you go down Group 7, the state of the elements at room temperature change from gas to solid.
• Group 7 elements get less reactive as you go down the group.
