Germanium

Source: Occurs naturally in rocks and minerals. Used in transistors and diodes prior to silicon. It is also used in fiber optics, infrared optical equipment, wide-angel camera lenses, and chemotherapy treatment.

Summary: Germanium is element 32 on the periodic table. The element was named after the country Germany. It has a density of 5.323 g/mL at 25 C. It is naturally occurring in rocks and minerals. Germanium was used in transistors and diodes prior to silicon. It is also has applications in fiber optics. Oxides of germanium are used in optical instruments for its transparency to infrared radiation. It may see uses in camera lenses for its refraction properties. Research is being done on the effects of germanium in chemotherapy treatments.
