In 1886AD, Germanium was discovered by German chemist, Clemens Alexander Winkler. In 1885, a new ore was found in a mine near Freiberg, Germany. The ore contained silver and sulfur. Winkler isolated a new element from the ore and named it as germanium. The name germanium is derived from Germany, which is the native country of Winkler.

Chemical Properties. At a temperature of 250 °C, germanium slowly oxidizes to G e O 2. Germanium dissolves slowly in concentrated sulfuric acid, and is insoluble in diluted acids and alkalis. It will react violently with molten alkalis to produce [GeO 3] 2-. The common oxidation states of germanium are +4 and +2.

Germanium, atomic symbol Ge, has an atomic number of 32, and lies in group 14, on the periodic table, below silicon and to the left of arsenic. This element has four valence electrons. This makes it less reactive because it would require more energy to lose or gain four electrons. Germanium has an electronegativity of 2.01 (Pauling Scale).

Germanium is key to fibre optic cables and also used in high-speed computer chips and plastics as well as infrared radiation. The metal and its oxides are used in military applications like night ...

This Review examines progress in materials science and devices that has enabled key building blocks for germanium quantum technology, such as hole-spin …

The element is a gray-white metalloid. In pure state, the element is crystalline and brittle, retaining its luster in air at room temperature. It is a very important semiconductor. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 1010.
