Which element is more reactive, Potassium or Krypton?

There are many elements on the periodic table. All of these elements are different in various capacities. Krypton is an element on the periodic table that many people who are not knowledgeable about science may think that Krypton is very strong and reactive. This is because the only way that many people have heard about Krypton is because they have listened to about Kryptonite from the Superman comics.

People realize that Kryptonite is the problem that weakens Superman. Even though Kryptonite is fake and not real, the element Krypton which is similar in spelling is real. However, Potassium which is an element found in bananas is more reactive than Krypton. It may be surprising based on the fictional information that many people associate with this element.
