Answer

The metals, from most reactive to least reactive, are: 1. Magnesium 2. Zinc 3. Iron 4. Copper

Explain

## Step 1: The reactivity series is a list of metals arranged in order of decreasing reactivity. Metals at the top of the series are more reactive than those at the bottom. ## Step 2: The reactivity series is used to determine the reactivity of metals with other substances. For example, it can be used to predict whether a metal will displace another metal in a chemical reaction. ## Step 3: The reactivity series is generally used in the order of most reactive to least reactive. However, in this particular case, we are asked to list the metals from most reactive to least reactive. ## Step 4: The most reactive metals are those that are more likely to form positive ions and displace other metals in a chemical reaction. These are usually metals that are more likely to lose electrons. ## Step 5: The least reactive metals are typically those that are less likely to form positive ions and displace other metals in a chemical reaction. These are usually metals that are less likely to lose electrons. #
