Solution
Based on the reactivity, metals are arranged in a series in the decreasing order of their reactivity. This series is called the reactivity series. The highly reactive metals are placed at the top, medium reactive metals in the middle and the least reactive metals at the bottom.
According to the reactivity series. the correct order of reactivity for the given metals is:
Sodium > Aluminium > Iron > Copper > Gold
