Based on your answer in part B, arrange the five elements in order of their reactivity. Drag the most reactive element to the to
amm1812

Answer: Order of the elements from most reactive to least reactive is:

Mg >  Zn > Fe > H > Cu

Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.

As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.

The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.

Hence, the order of the elements from most reactive to least reactive is:

Mg >  Zn > Fe > H > Cu

Reactivity series is attached below.
