Germanium is a chemical element; it has symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid or a nonmetal in the carbon group that is chemically similar to silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

Mar 3, 2025 · 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 nonmetals.

Germanium (pronunciation: jer-MAY-ni-em) is a shiny, silvery element classified as a metalloid and represented by the chemical symbol Ge [1, 2]. As a relatively inactive element, germanium does not react with oxygen at 20°C and is insoluble in water but its compound, germanium dioxide, is slightly soluble in water [3].

Aug 25, 2016 · Germanium is a silvery white metalloid. This is a 2-by-3 centimeter piece of polycrystalline germanium, weighing about 12 grams.(Image credit: Jurii/Creative Commons) Shiny and silvery, yet...

Germanium is an abundant element and is ranked as the 15 th most abundant element in the earth’s crust. Germanium is not present in its pure elemental form and mostly extracted from its zinc ore (sphalerite) and from ores of copper, silver and lead.

Germanium is a chemical element placed between silicon and tin in Group 14 of the periodic table. A hard, grey-white, lustrous and brittle metalloid acts in properties between metals and nonmetals. The element is mostly distributed in nature, but it’s too reactive to occur free.

Jun 25, 2019 · Germanium is a rare, silver-colored semiconductor metal that is used in infrared technology, fiber optic cables, and solar cells.

Jan 21, 2025 · Germanium is a chemical element with the symbol ‘Ge’ and atomic number 32. It’s a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Germanium is used primarily in semiconductors and fiber optics, known for its ability to conduct electricity in a controlled manner.

A metalloid in group IVa of the periodic table along with carbon, silicon, tin, and lead; Comparatively low systemic toxicity: injures the kidneys, liver, and nerves; Topical application of Ge dioxide caused no irritation, but Ge tetrachloride, which hydrolyzes releasing HCL, caused ulcerations after 2 hours; Oral LD50 (rat) = 3700 mg/kg; Toxic ...

Germanium belongs to the semimetals in the periodic table. Germanium is one of the rarest metals on earth. The shiny silver element melts at just under 940 °C and boils at 2,820 °C. It is considered a semiconductor, comparable to silicon.
