Germanium is used mainly today in electrics, light-emitting diodes, fiber-optics, and semiconductors.
Fun Fact! Like water, liquid germanium is unusual because it expands when it freezes.
Some germanium compounds may have medical applications because they appear to kill bacteria without harming animals.
