13) This element is more reactive than sodium and calcium but less reactive than rubidium. Thus, in potassium, the. The tendency to loose electrons is greater in potassium than that in lithium. Therefore potassium is the most reactive metal within the given metals. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. Similarly, calcium is more reactive than magnesium. It can also float on water surface, is light weight and can easily be cut by a knife. It follows, therefore, that this outermost electron is more easily lost than it is in sodium, so potassium can form K+ more readily than sodium can form Na+. Hence, potassium is more reactive than sodium. It is an alkali metal, and they become more reactive as you go down the group from lithium to sodium to potassium etc. Exposed to water, it explodes with a purple flame, so it's usually stored under mineral oil for safety.
