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 (more rarely considered a metal) in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms ...
Germanium compounds are chemical compounds formed by the element germanium (Ge). Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ([GeO. 3]2−. ). Germanium occurs mostly in the oxidation state +4 although many +2 ...
Infobox references. Germanium dioxide, also called germanium (IV) oxide, germania, and salt of germanium, [1] is an inorganic compound with the chemical formula Ge O 2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride.
Germanate. In chemistry, germanate is a compound containing an oxyanion of germanium. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central germanium atom, [1] for example potassium hexafluorogermanate, K 2 GeF 6. [2]
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Sodium germanate is an inorganic compound with the chemical formula Na 2 GeO 3. It exists as a colorless solid. Sodium germanate is primarily used for the synthesis of other germanium compounds.
Germanide. A germanide is any binary compound of germanium and a more electropositive element. The composition of most germanides is analogous to that of the corresponding silicides and does not follow formal valence rules. The germanides of alkali and alkaline earth metals, are readily decomposed by water and acids to give germanium hydrides ...
Organogermanium chemistry is the science of chemical species containing one or more C – Ge bonds. Germanium shares group 14 in the periodic table with carbon, silicon, tin and lead. Historically, organogermanes are considered as nucleophiles and the reactivity of them is between that of organosilicon and organotin compounds.
