Groups of the Periodic Table

Comprehension and additional task exercises pages 94 and 95 from Next Page Science KS3 Complete. Accompanying PowerPoint and word searches available for free from the website.
This exercise covers:
• The properties of Group 1, Group 2, Group 7 and Group 8
• The alkali metals: reaction with water (alkaline solution and hydrogen gas formation), pattern in reactivity down the group, density and melting points pattern. All have only one electron in their outer shell as the reason for the similarities
• The alkali earth metals: reaction with water, pattern in melting points, boiling points and density. All have two electrons in their outer shell as the reason for the similarity
• The Halogens: patterns in melting and boiling points, decrease in reactivity down the group and chlorine’s use as a disinfectant. All have seven electrons in their outer shells as the reason for the similarities.
• The noble gases: their use in ‘neon’ lights. All having a full outer shell as the reason for their unreactivity.
• A melting point and boiling point plotting exercise on the alkali metals
