The order of reactivity is Al > Mn > Cr.

What is the activity series?

The activity series is a series that shows the increasing order of reactivity of elements. For metals, the more reactive elements occur at the top, the moderately reactive elements occur at the middle while the unreactive elements occur below.

Aluminum is the most reactive followed by manganese and lastly followed by chromium.
