Potassium
Explanation
## Step1:The reactivity series of elements is a list of metals arranged in the order of their decreasing activities. The most reactive metal is placed at the top and the least reactive metal at the bottom. ## Step2:Given the reactivity series in the question, we can see that Sodium is the second element. The element that is more reactive than Sodium and should be placed at the top of the series is Potassium.## Step3:Therefore, the metal that goes in gap 1, which is more reactive than Sodium, is Potassium.
