Reactions of Germanium |
Reactions with water |
The thin oxide layer renders germanium more or less inert to water. |
Reactions with air |
The surface of lumps of germanium is protected by a very thin layer of germanium dioxide. At red heat, germanium reacts with oxygen in air to from germanium dioxide. |
