potassium

sodium

calcium

Answer 2

◆Definition: The arrangement of metals in a series according to the decreasing order of their reactivity is called reactivity series.

◆◆The metals that are placed above hydrogen are more reactive and those below hydrogen are less reactive.

◆◆ A metal placed above another metal can displace lower metal from its salt solution. Thus a metal placed above in series is more reactive than metals placed below it.
