A science teacher is planning a demonstration to illustrate the trend in reactivity of the Group 1 (alkali) metals when they react with water.
They have access to lithium, sodium, and potassium, and will use these observations to help students predict the reactions of the elements further down the group, namely rubidium and francium.
Describe the expected observations for the reactions of lithium, sodium, and potassium with water, and explain how these observations allow us to predict the chemical behaviour of rubidium and francium.
In your answer, you should also:
Practise Edexcel GCSE Chemistry Group 1 with exam-style questions for Foundation and Higher tier. 51 questions, matched to the Edexcel GCSE Chemistry (1CH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
