Experiment
Heating Group 1 metals in air and in chlorine
This is a demonstration that shows the reactions of Group 1 metals in air and in chlorine. It does not clearly show the trends in reactivity of Group 1 metals, which are better demonstrated by the reactions in water, which follow on well from this demonstration.
