The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)
Caesium is most reactive element
Noble gases are least reactive elements
