Group 1 part 1

This video is for the new GCSE specifications (levels 1-9) for all exam boards. In this video, we look at group 1 – the alkali metals. First we look at how the alkali metals react with oxygen and how they get more reactive as we move down group 1. We then look at this reaction in terms of electron movement. Finally, we explore how the alkali metals react with chlorine gas.
