Germanium is mined primarily from sphalerite (the primary ore of zinc), though germanium is also recovered commercially from silver, lead, and copper ores. Elemental germanium is used as a …

5 days ago · germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the …

Germanium is a semiconductor. The pure element was commonly doped with arsenic, gallium or other elements and used as a transistor in thousands of electronic applications. Today, however, other …

Germanium’s graphical representation features an image of a transistor, which indicates the early use of the element [1]. Being a metalloid, germanium has the properties of both nonmetals and metals [6].

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass.

Aug 25, 2016 · The existence of germanium was predicted by Russian chemist Dmitri Mendeleev in 1869, after he developed the periodic table of elements, according to Chemistry Explained.

The existence of germanium was predicted by Russian chemist Dmitri Mendeleev (1834-1907), who developed the periodic table. Mendeleev predicted a new element would be found to fill an empty …
