The discovery and uses of reactive metals throughout history, and how their uses have defined the period in which they were discovered.Key facts
- The reactivity series ranks the chemical reactivity of elements.
- Reactive metals will combine with other elements to form a compound.
- Native elements are unreactive and found as pure elements in the earth.
- Heating and electrolysis are used to extract metals.
Transcript
Our relationships with different metals have defined whole periods of human history.
The order in which we have exploited metals comes down to their chemical reactivity, a ranking known as the reactivity series.
The more reactive a metal is, the more likely it is to combine with other elements to form a …
