2020-2-18 · The more reactive a metal is the more likely it is to form a compound. The more reactive a metal, the more stable its compound. The more reactive a metal the more difficult it is to extract from its compounds. Copper, silver and gold appear as elements in the earth due to their unreactivity with their environment. They are easy to extract.
