Answer 1

Answer:

Metals in the decreasing order of their chemical reactivity placing the most active first. The metals are Cu, Mg, Fe, Na, Ca, Zn.

therefore, There is the order of reactivity of metals and in order to remember this order, one has to recite this order in any possible simple form. The order of reactivity of metals is as follows, Copper > Magnesium > Iron > Sodium > Calcium > Zinc.
