The order of reactivity series is Most reactive metals are at the top while the least reactive metals are at the bottom.
A reaction series is a list of metals arranged in descending order of reactivity. The most reactive metals are on top and the least reactive metals are on the bottom. If there are any two metals in the column, the metal placed at the top of the column can displace the bottom metal from the brine.
The more reactive the metal the faster the reaction. Metals below hydrogen in the reaction sequence do not react with dilute acids. Platinum is placed below gold in the reaction sequence. The elements in the lower left corner of the periodic table are the most active metals in the sense that they are the most reactive.
