The global minimum of XMg 4 Y − (X = Si, Ge; Y = In, Tl) and SiMg 3 In 2 contains a planar pentacoordinate atom of group 14 other than carbon. Its design is based on the “localization” approach, replacing one or two peripheral atoms in XMg 5 2− by more electronegative ones. This change diminishes the repulsion and leads to stronger covalent X–Y bonds, stabilizing the planar. Germanium is solid, shiny chemical element with the symbol Ge. This element has atomic number of 32 and atomic weight of Germanium is grouped as the metalloid element which means that this carbon group element possesses both metallic and non-metallic chemical element properties.

The first part of the book introduces readers to the fundamental properties of germanium, such as band offsets, impurities, defects and surface structures, which determine the performance of germanium-based devices in conjunction with conventional silicon technology.
Germanium has a diamond-like structure and its properties are very similar to the physical and chemical properties of silicon. It is stable in air and water and does not get affected by alkalis and acids except nitric acid.
There are primary minerals which Atomic Mass: It is extracted from the ore with hydrochloric acid, and the resulting germanium tetrachloride, GeCl 4, is purified by fractional distillation.
Hydrolysis and then heating yields germanium dioxide, GeO 2, which is reduced by carbon or hydrogen to yield the free element. Germanium is.
What is the Atomic Number of Germanium. Germanium is a chemical element which is placed in the 14th group and 4 th period in the periodic table. Symbol of the germanium element is Ge. It is a metalloid with the atomic number As germanium is a metalloid, it shows some properties of metals and nonmetals as well.
As a semiconductor, germanium allowed the production of a solid state equivalent to the diode. Like most semiconductors, germanium can have impurities added to make it an electron donor - a so-called n-type material - or an electron acceptor, called p-type. By marrying p and n type strips of germanium, the element provided the same diode effect.
Germanium is a metalloid. A metalloid is an element that has characteristics of both metals and non-metals. At the time, Winkler was professor of chemical technology and analytical chemistry at the Freiberg School of Mines.
He was convinced that the new ore contained a new element. He isolated the new element from the ore and named it.
Germanium (Ge) is considered a critical element due to its many industrial applications; Ge is a metalloid used in solar cells, fiber optics, metallurgy, chemotherapy, and polymerization catalysis.
The main sources of Ge are sulfides ores of Zn, Pb, and Cu, coal deposits, as well as by-products and residues from the processing of these ores and coals (e.g., smelting flue dust and coal fly ashes). CHEMISTRY OF GERMANIUM GENZRAL IU3VIEWSOF ‘1’HE III.

It is classified as a metalloid. It is similar in properties to the other metalloids near it in the periodic table which are silicon and arsenic.
Germanium atoms have 32 electrons and 32 protons with 4 valence electrons in the outer shell. ISBN: OCLC Number: Notes: "A Halsted Press book." Translation of Analiticheskai︠a︡ khimii︠a︡ germanii︠a︡.

Germanium annual survey covering the year Journal of Organometallic Chemistry48 (1), DOI: /SX(00) Germanium is a chemical element with the symbol Ge and atomic number It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbours silicon and germanium is a semiconductor with an appearance similar to elemental silicon.
Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Acidity, Complexing, Basicity and H‐Bonding of Organic Germanium, Tin and Lead Compounds: Experimental and Computational Results (Pages: ) Axel Schulz Thomas M. Klapötke. 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 gh germanium was not discovered until by Clemens Winkler, a German chemist, its existence, properties, and position in the periodic system had been predicted in by the Russian chemist.
Germanium is brittle and silvery-white under standard conditions. Germanium under this condition is known as α-germanium, which has a diamond cubic crystal structure.
When germanium is above kilobars, germanium has a different allotrope known as β-germanium. Germanium is one of the few substances like water that expands when it solidifies.The chemistry of germanium Academic P London, New York Australian/Harvard Citation. Glockling, F.
