What is the reactivity series?
The reactivity series is an order of metals based on how readily they react with other substances. It includes metals and often carbon and hydrogen for comparison.

What is the reactivity of metals that are at the top of the reactivity series?
Metals at the top of the reactivity series are very reactive.

What is the reactivity of metals at the bottom of the reactivity series?
Metals at the bottom of the reactivity series are unreactive.

Explain how the reactivity of a metal determines its extraction method.
Metals more reactive than carbon are extracted by electrolysis.
Metals less reactive than carbon and more reactive than hydrogen are extracted using reduction with carbon.
Metals less reactive than hydrogen are found in their native state.

What is electrolysis in the context of metal extraction?
Electrolysis is a process that involves using electricity to split the ore compounds and extract the metal.

What is reduction with carbon in the context of metal extraction?
Reduction with carbon is a process that involves heating the metal ore with carbon to remove oxygen as CO2, leaving pure metal behind.

What does it mean for a metal to be found in its native state?
A metal being found in its native state means that it is found as a pure element in nature.
