Explain why sodium is more reactive than Lithium? (4 marks)

Na has more electron shells/ energy levels than Li. This means that Na has a greater atomic radius than Li. Therefore, the outer shell electron in Na experiences a weaker nuclear attraction than in Li. Less energy is subsequently required to remove the outer shell electron in Na than Li/ the outer shell electron is more easily lost in Na
