The arrangement of metals in a vertical column in the decreasing order of their reactivities is called the reactivity series or activity series of metals. The most reactive metal is at the top position of the reactivity series. The least reactive metal is at the bottom of the reactivity series.
Hydrogen, though non-metal, has been included in the activity series of metals only for comparison. Apart from it, the hydrogen atom also has a tendency to lose its valence electron and form a cation that behaves like a metal.
