Oxide - Wikipedia

Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals . This reactivity is the basis of many practical processes, such as the extraction of some metals from their ores in the process called hydrometallurgy .
