Reactivity Series

Question

What is 'reactivity series'? Arrange the metals Al, Zn, Mg, Cu and Fe in the decreasing order of reactivity.

Answer 1

The reactivity series is a list of metals arranged in order of their reactivity, from the most reactive to the least reactive. It helps predict how metals will react with acids, water, and other substances.

For the metals you mentioned, here they are in decreasing order of reactivity:

1. Magnesium (Mg)

2. Aluminium (Al)

3. Zinc (Zn)

4. Iron (Fe)

5. Copper (Cu)

Magnesium is the most reactive among these, while copper is the least. Now you know your metal hierarchy!

Answer 2

The reactivity series is a list of metals arranged in order of decreasing reactivity. It helps to predict how metals will react with water, acids, and other substances. The more reactive a metal is, the more readily it will react.

The general order of reactivity for the metals you mentioned is as follows:

1. Magnesium (Mg)
2. Aluminum (Al)
3. Zinc (Zn)
4. Iron (Fe)
5. Copper (Cu)

So, in decreasing order of reactivity, the arrangement is:

Mg > Al > Zn > Fe > Cu

This means magnesium is the most reactive among these metals, while copper is the least reactive.
