What are the features of the reactivity series of metal?

Solution

Reactivity series is the series of metals based on their reactivity from highest to lowest.

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions.
