21.7 Oxygen Is Responsible for Corrosion and Combustion

Electroplating to Protect Metals

Electroplating is the process whereby energy is used to force a metal to give up electrons. The metal ions that form then pick up electrons at some surface where they reform the metal atoms and thus form a thin coat of metal. Duration: 5:52.

Combustion is a process whereby a nonmetallic material, such as paper, oxidizes (loses electrons) with the release of lots of energy. Typically, the reagent responsible for gaining the electrons is the oxygen in our atmosphere. Duration: 7:45.
