germanuim

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, which has a similar crystalline structure to diamond. Germanium is a semiconductor, with an appearance similar to silicon. It is more reactive than silicon and forms a protective oxide layer when exposed to air. Germanium is used in various applications, including electronics, optics, and medicine. It is also used as a catalyst in the production of polyethylene terephthalate (PET) and as a dopant in the production of silicon-based semiconductors. Germanium was discovered in 1886 by Clemens Winkler, who identified it in the mineral argyrodite. The name "germanium" comes from the Latin word "Germania," referring to Germany, where the mineral was found. Germanium is not known to have any biological role and is considered non-toxic in its elemental form. However, some of its compounds are toxic.
