Explanation:
The order of intensity of reactivity is known as reactivity series. Reactivity of element decreases on moving from top to bottom in the given reactivity series.
In the reactivity series, copper, gold, and silver are at the bottom and hence least reactive. These metals are known as noble metals. Potassium is at the top of the series and hence most reactive.
Reactivity of some metals are given in descending order
K > Na > Ca > Mg > Al > Zn > Fe > Pb > Cu
