Explanation:

The activity series shows the order of reactivity of metals. Metals that are high up in the series are highly reactive. These highly reactive metals will not exist alone in the ground. They combine with elements such as oxygen, sulphur, etc to form ores.

Other metals that are found much lower in the activity series are largely unreactive. They exist in the ground as pure metals, examples include silver and gold
