Answer 2

$\large \bold{ \underline{ \underline{ \sf \: Answer : \: \: \: }}}$

$\to$ Reactivity series is a list of metal arranged in the order of their decreasing activities

$\to$ On the basis of their relative tendency to lose electron and their reactive nature , metal are arranged in a series , this series is called reactivity series

$\to$ Reactivity series is also called as activity series

$\to$ Note : Hydrogen also have non metallic properties but due to its electropositive nature , it has been placed in the reactivity series
