There are three common methods of obtaining metals from the Earth's crust:
The method chosen to extract a metal is directly linked to its position in the reactivity series.
Platinum, sodium, zinc, and lead are four metals with different reactivities.

Use the reactivity series in Figure 1 to state and explain the method chosen to extract each of these four metals.
