Why are most metals found in the earth as compounds?

Answer 1

Because metals are good reducing agents.

Many metals occur naturally as oxides or sulfide ores; as such, they are good reducing agents because they are species rich in electrons.

Gold, which is still found in pure form, is one of the few metals that is not as reactive, which is why there were gold rushes on two continents a few centuries ago.
