Gabriel and Carrter are conducting cting an experiment to determine which metal is most reactive. Which metal should they choose? potassium sodium lithium rubidium

## Step 1<br />The reactivity of metals is determined by their ability to displace other metals from their compounds. This is known as the reactivity series of metals.<br /><br />## Step 2<br />The reactivity series of metals is a list of metals arranged in order of their decreasing chemical reactivity. The most reactive metal is at the top of the list, and the least reactive metal is at the bottom.<br /><br />## Step 3<br />The reactivity series of metals, from most reactive to least reactive, is as follows: Potassium, Sodium, Lithium, Rubidium.<br /><br />## Step 4<br />From the reactivity series, we can see that Potassium is the most reactive metal among the options given.
