The series of metals arranged in the decreasing order of their reactivity is called the activity or reactivity series.
The most reactive metal is placed at the top, and the least reactive one is placed at the bottom of the series.
Metals above hydrogen may displace hydrogen from water and dilute acids, but the metals below hydrogen cannot displace hydrogen.
The metal which has more reactive than hydrogen (K, Na, Fe...etc)then they displace hydrogen from dilute acids. 2HCl + 2Na → 2NaCl + H₂ gas released
